Development of a thermal camera for RPAS used to monitor the water status of crops
type: item
description: Monitoring and evaluating crop water status is critical to optimizing water use and promoting sustainable agricultural production. The measurement of canopy temperature using thermal images has established itself as a reliable technique for estimating plant water status; however, its adoption is limited by the high cost of thermal cameras and unmanned aerial systems. Due to the above, a low-cost thermal camera was developed based on the 32 × 24 pixel MLX90640 infrared sensor and the Teensy 3.6 microcontroller, with storage capacity on a microSD card. The device was integrated into an unmanned aerial system and evaluated in a corn crop, with its measurements compared with those of a LI-COR LI-1600 porometer (accuracy ±0.5 °C). The thermal images were enhanced by bicubic interpolation and fused with RGB images to obtain images with a resolution of 640 × 480 pixels, which were then processed and segmented using binary images to isolate the pixels corresponding to the crop canopy temperature. Subsequently, the temperature values from the thermal images and the LI-COR LI-1600 porometer at each sampling site were compared, yielding a root mean square error of 0.74 °C. The results show that the developed thermal camera offers adequate accuracy, low cost (135 USD), and high spatial representativeness, positioning itself as a promising tool for thermal canopy monitoring in precision agriculture and efficient water resource management applications.

Impact of thidiazuron on floral induction, yield and fruit quality of Malus domestica Borkh.
type: item
description: In the Northeastern Sierra of Puebla, the ‘Criolla’ apple has remained in production; however, the cultivar cannot compete in markets with commercial cultivars, and its production has decreased due to climate change. With the aim of increasing the percentage of flower bud break and the production in apple trees of the ‘Golden Delicious’ and ‘Criolla’ cultivars, applications of the bud break promoter thidiazuron (TDZ) were carried out in Mexcalcuautla, Teziutlán, Puebla, during the 2022 and 2023 cycles. The trees received 400 and 600 ppm TDZ; a 2x3 split-strip arrangement was used, limited to six treatments in a randomized block experimental design; flower and vegetative bud break, inflorescence, fruit set, yield and physical and biochemical aspects of fruit were evaluated. Statistical analyses indicated that ‘Golden Delicious’ apples with 400 ppm TDZ presented higher flower bud break and yield. The physical quality of the fruits was better in ‘Golden Delicious’ with 400 ppm TDZ and ‘Criolla’ without TDZ since their fruits had a greater weight; in terms of the size and respiration rate of the apples, there were no differences between the treatments; nevertheless, firmness was higher in ‘Golden Delicious’ apples with 400 ppm TDZ than in the other treatments. The content of malic acid, ascorbic acid, pH, total soluble sugar content and starches were not affected by TDZ applications. It was concluded that applying TDZ at 400 ppm increased the percentage of flower bud break in ‘Golden Delicious’ apples and did not harm the physical and biochemical quality of the fruits.

Intrinsic and extrinsic attributes influencing the selection of dehydrated fruits and vegetables in Mexico
type: item
description: For dehydrated products to access new markets and for their production to generate economic development opportunities in rural production units, it is necessary to understand consumer demands. The objective was to analyze consumer behavior and identify the main attributes that lead consumers to make the decision to purchase dehydrated fruits and vegetables in Mexico in 2023. A survey was administered to 704 households nationwide and analyzed using Pearson correlation, cluster analysis and the analytic hierarchy process (AHP). It was identified that the most valued attributes were flavor (46.28%), being a national product (40.13%), biodegradable packaging (38.04%), and supporting environmental conservation (35.42%). In addition, four groups of consumers were identified who differed in the attributes valued when purchasing dehydrated products; however, flavor was the most important across all groups. Companies that produce dehydrated fruit and vegetable products can create generic promotion strategies that highlight the attributes of health, environmental care, product quality and social responsibility.

Characterization of bean seeds from Ñäñho communities of Amealco, Querétaro
type: item
description: Beans are one of the main components of traditional Mexican gastronomy. Mexico is the center of origin, domestication, and diversification of Phaseolus vulgaris and P. coccineus. These are cultivated in the Ñäñho communities of Amealco, Querétaro, Mexico; however, their characteristics are unknown. The work aimed to determine inter and intraspecific seed diversity based on morphological characteristics and chemical composition. The study was conducted in 2024 at the Faculty of Natural Sciences of the Autonomous University of Querétaro. Twenty-one accessions (eight of P. coccineus and 13 of P. vulgaris) held in safekeeping at the Germplasm Bank-UAQ, which were collected in 2021 and 2022 in San Miguel Tlaxcaltepec, San Ildefonso and Santiago Mexquititlán, communities of the municipality of Amealco, Querétaro, were analyzed. Four quantitative morphological variables and 11 qualitative variables of each accession’s seeds were measured. In addition, chemical analysis was carried out, determining ash, moisture, crude protein, ethereal extract, crude fiber and nitrogen-free extract contents. Statistically significant differences were found in size, weight and protein contents between the two species. Intraspecific diversity was identified in the two species, mainly defined by seed color and size, as well as by percentages of ethereal extract and crude fiber. The Ñäñho communities of Amealco, Querétaro, present inter- and intraspecific diversity in both species, with a higher protein content in P. vulgaris than in P. coccineus.

Analysis of the factors determining coffee production in Mexico
type: item
description: Coffee is one of the most important agricultural crops in Mexico due to its economic and social relevance and because it generates income in rural areas, placing the country in the fourteenth place worldwide as a producer. In order to identify the economic factors that determine national coffee production, an econometric study was conducted in Mexico for the 1960-2024 period. A multiple linear regression model was applied based on time series obtained from official sources such as INEGI, SADER, OIC and Banxico. The dependent variable was coffee production, explained by the cultivated area, international prices, real input prices and production lags. The results show a high level of fit (R²= 0.974; Fcalculated= 207.72> Ftabulated= 2.15), indicating that the selected variables significantly explain the variations in production. It was found that the cultivated area, lagged production and two- and four-period lagged prices positively influence production, while international prices and some price lags have negative effects. In conclusion, Mexican coffee production depends mainly on the cultivated area and the behavior of production in previous years, reflecting the temporal persistence characteristic of this perennial crop.

Competitiveness of coffee production in Chiapas
type: item
description: In Mexico, most of the coffee-growing sector consists of peasant and indigenous families, and coffee is produced on small plots. For the state of Chiapas, coffee production is the main source of income, and the state ranks first nationally in coffee production and exports, being considered competitive; however, it has dropped to 12th place internationally. Regarding income, it should be a profitable production, with profits to meet the family needs of coffee growers. The objective was to evaluate the competitiveness and comparative advantage of small coffee producers in three regions of the state of Chiapas by analyzing their costs, income, and profitability in order to generate marketing alternatives that reduce costs and improve their profits. The hypothesis is that, in coffee production, producers obtain positive net income from their traditional production tasks, which determine competitiveness for the study regions. The research project was conducted using a mixed-methods (quantitative and qualitative) approach in the 2021-2022 production cycle in three regions of the state of Chiapas: San Juan Cancuc, Ángel Albino Corzo and Sitalá, applying the policy analysis matrix. The results indicate that the three study areas are profitable and competitive and that they have a comparative advantage. Coffee production for the study areas is profitable and competitive, has a comparative advantage and can be improved by considering the political intervention towards small producers for improvements in their crops, which will have positive effects on plant yield, thereby obtaining quality products that can be better paid and strengthening coffee growers to improve the ability to market their product and encourage the expansion of the production area.

Effect of vermicompost on Williams banana seedlings in a nursery
type: item
description: Vermicompost is an organic amendment of broad interest in sustainable agriculture, as it improves substrate fertility and exerts suppressive effects against pests and diseases. The objective of the present research was to determine the effect of vermicompost on the growth of banana seedlings in the nursery stage. Four treatments were established: T1 (100 g vermicompost + 650 g rice husks + 650 g sand); T2 (200 g vermicompost + 600 g rice husks + 600 g sand); T3 (300 g vermicompost + 500 g rice husks + 500 g sand); and T4 (control: 0 g vermicompost + 500 g rice husks + 300 g soil + 500 g sand). Parameters related to aerial and root growth were evaluated, including height, pseudostem diameter, leaf emission, chlorophyll content, root and corm weight, as well as root length. The results showed that vermicompost favored the development of seedling morphology, especially at the 300 g dose, which increased pseudostem robustness and leaf emission. These findings confirm the potential of vermicompost as a sustainable tool to strengthen the health, productivity and quality of banana plants in a nursery.

Effect of pollen carriers on cherimoya production in the Andean region
type: item
description: The research aimed to evaluate the effect of pollen carriers on cherimoya (Annona cherimola Mill.) production through the use of assisted pollination under conditions of the high Andean zone of the Lima region, Peru. The design used was a randomized complete block design with six treatments and three replications. The treatments were: T1) pollen carrier with chuño flour (potato starch); T2) pollen carrier with Lycopodium clavatum flour; T3) pollen carrier with white corn flour; T4) pollen carrier with wheat flour; T5) pollen carrier with industrial talc; and T6) natural pollination (control). Each experimental unit consisted of three trees arranged in a 48 m2 area. The variables evaluated were the number of fruits set per tree, yield by fruit category (t ha-1), and total yield (t ha-1). The averages were compared using the Scott-Knott test at 5% level. It was found that treatment with L. clavatum flour significantly outperformed all other treatments, obtaining more fruits set per tree, higher total yield, and higher yield in each of the categories considered; it was followed in importance by chuño flour. The control treatment produced the lowest values for the set of characteristics evaluated and was statistically lower (p< 0.05) than the other treatments. It is concluded that assisted pollination with pollen carriers significantly increases cherimoya production, with treatments with L. clavatum flour and chuño flour standing out.

Seed regulation: challenges and perspectives of Mexican law
type: item
description: In Mexico, the Federal Law on Seed Production, Certification and Trade was enacted in 2007; its main objective is to regulate the production, qualification and trade of seeds, seeking to organize and improve the national agricultural sector. This paper analyzes, through a documentary review, the impact of this legislation on the protection and conservation of native seeds in Mexico. Currently, the legal framework, by pointing to a model for the production and certification of ‘improved’ and commercial seeds, systematically marginalizes native varieties and peasant seed systems, which are essential for agricultural resilience and long-term food security. The study concludes that, despite its objectives, the law inadvertently contributes to the loss of agrobiodiversity and genetic erosion in the country. The lack of description guides and the limited inclusion of native varieties in the National Catalog of Plant Varieties leave an invaluable genetic and cultural heritage in a situation of vulnerability.

Adaptation of Prunus serotina to rehabilitate degraded semi-arid soils
type: item
description: The rehabilitation of degraded soils in semi-arid areas requires woody species with high water-stress tolerance and the potential to provide ecosystem services. Prunus serotina has been characterized as tolerant to water stress and having low soil requirements, in addition to presenting rapid growth; however, there is little recent evidence on its initial performance in semi-arid conditions in Mexico. The objective was to evaluate the early adaptation of P. serotina in the field and to estimate its regional environmental suitability. The study was conducted from 2021 to 2022 in Nopaltepec (Tula River Basin, State of Mexico, Mexico). A plantation trial was established with survival and growth monitoring; survival was analyzed using the Kaplan-Meier estimator and factors associated with mortality risk were analyzed using a Cox proportional hazards model. Environmental suitability was modeled with MaxEnt using bioclimatic and topographic variables; performance was verified using AUC and TSS and a suitability map was generated.

Cytokinins and pH on the in vitro culture of strawberry shoots
type: item
description: Conventional strawberry propagation is performed using runners, which may limit the number and health of plants. The present work assessed the effects of different culture media variants on shoot proliferation in vitro, shoot size and root formation. Seventy-seven variants of culture media were prepared with inorganic salts of the Murashige and Skoog (MS) formulation, different concentrations of two cytokinins, benzylaminopurine, BAP (0, 0.5 and 1 mg L-1) and thidiazuron TDZ (0, 0.5 and 1 mg L-1) and different pH levels (5, 5.5 and 5.8). Data was taken on the number of shoots, the number of leaves and root formation. The data were subjected to analysis of variance and Tukey’s test (0.05). The highest number of shoots (11), with up to 57 leaves, was obtained in the culture medium with 0.5 mg L-1 TDZ, 0 mg L-1 BAP and a pH of 5.5. The lowest numbers of shoots (2.3), with 18 leaves, were obtained in CM without TDZ, 0.5 mg L-1 BAP and a pH of 5.5. In environments with only BAP, the new shoots were taller and formed adventitious roots. TDZ inhibited root formation. It is concluded that the presence of TDZ in CMs stimulated more axillary buds to sprout, while BAP promoted the development of axillary buds but with a lesser effect than that of TDZ.

Fertigation and Azospirillum in the nutrition of Agave angustifolia vitroplants in a nursery
type: item
description: Humanity seeks to increase the productivity and quality of crops that provide basic or economic benefits. The work aimed to evaluate the development of Agave angustifolia vitroplants fertigated with different nutrient aliquots and inoculated with Azospirillum brasilense from 2023 to 2024. In an experiment with a 3 × 2 × 3 factorial experimental design, the factors were: 1) initial plant size (small, medium, and large); 2) inoculation with the bacterium A. brasilense and without inoculation; and 3) concentrations of the Steiner nutrient solution (SN) (0, 75 and 100%). After 20 months, morphological characteristics and the amount of nutrients in the leaves were evaluated. Plants with a larger initial size maintained differences in growth compared to medium and small plants. The plants fertigated with 100% SN had a height of 51 cm (18.6%), a rosette diameter of 85.8 cm (25.8%) and a stem diameter of 9.6 cm (65.5%). Their largest leaf was 66 cm (13.7%), and their leaves contained 6 987 ppm N (9.6%), 1 775 ppm P (11%), and 3 093 ppm K (-25.8%) compared to plants irrigated only with water. The plants inoculated with the bacterium had more leaves, a larger rosette diameter, greater leaf length, greater root volume and greater stem and root dry weight than non-inoculated plants. The micropropagated A. angustifolia plants that were fertigated in a nursery and in parallel, inoculated with A. brasilense reached adequate sizes for transplantation in the field.

Asymmetries of the yellow and white corn markets in Mexico
type: item
description: The study focuses on analyzing the yellow and white corn markets in Mexico during the period 2010-2023 to understand the current situation of both grains and to generate a background that allows the development of studies differentiated by corn variety rather than treated as a homogeneous crop. Distinguishing between corn varieties allows us to understand the productive, price and trade dynamics, where white corn is intended for food diets and yellow corn for livestock consumption. This study aimed to estimate and identify asymmetries in competitiveness, trade balance and prices, using indices of self-sufficiency and import dependence, as well as the relative prices proposed by FAO and the World Bank. The results showed significant differences; on the one hand, yellow corn is dependent on imports, has limited domestic production and has relative prices that, although competitive as of 2020, show a loss of profitability; on the other hand, white corn has productive self-sufficiency and a strengthened national production; however, it is not present in the international market (exports and imports) and relative prices, while showing a growing trend in competitiveness, are also losing profitability. In conclusion, it is recommended that the State intervene through differentiated agricultural policies that include contract farming for yellow corn and technological improvements and fertilizer subsidies for white corn, in order to improve profitability and thereby promote national production.

Moisture levels and densities on bean yield
type: item
description: The research evaluated the effect of three soil moisture levels (30%, 70% and 100% of usable moisture) combined with two densities (30 and 40 plants m-2) on the yield of the bean (Phaseolus vulgaris L.) crop, variety Pinto Saltillo, under drip irrigation in Salinas de Hidalgo, San Luis Potosí. The design used was a 3 × 2 factorial design with three replications, totaling 18 experimental units. The variables analyzed included plant height, stem thickness, leaf dimensions, number of pods, plant dry weight, pod weight and grain yield. The treatment with 30% moisture (90 000 L ha-1 per irrigation) and 30 plants m-2 presented the best performance, reaching 47 cm in height, 15 pods per plant and a yield of 118 g m-2 (1 180 kg ha-1). Treatments with 70% (210 000 L ha-1 per irrigation) and 100% moisture (300 000 L ha-1 per irrigation), together with higher density, showed negative effects due to intraspecific competition. There were no significant differences in yield across moisture levels, even when irrigation volume was doubled or tripled. Significant correlations were identified between height and number of pods (r= 0.716), pod weight and grain yield (r= 0.987) and leaf dimensions (r= 0.887). The results indicated that moderate water stress and adequate density favor bean development and allow efficient water use. The study provided technical evidence to optimize water management and agronomic practices in semi-arid regions.

The export of the guava from Mexico to the world market
type: item
description: Guava is a fruit widely accepted worldwide and in 2023, Mexico consolidated its position as the second-largest global exporter, with a value of 577 934.18 USD, confirming its high international competitiveness. The research aimed to analyze the competitiveness of Mexican guava in international trade, identifying its position and formulating alternatives that strengthen its insertion into international trade. The research was conducted by calculating growth rates and trade competitiveness indices for the period 2000-2023, using production and foreign trade data. The results showed that the indicators were positive: the trade balance remained at 1, which confirms that Mexico is an exporter with competitive advantages; the tradability indicator was 0.34, evidencing an excess of exportable supply; the trade dependence coefficient was 0, which reflects food self-sufficiency; and the degree of export openness reached 0.035, pointing out the existence of exportable surpluses. Overall, these results indicate that guava production in Mexico is expanding, with a marked export specialization and a solid competitive position in the international market. t.

Evaluation of drought indices in crystalline wheat genotypes
type: item
description: Wheat is an important cereal for the human diet due to its protein and caloric contribution; however, production by 2050 will be compromised by the effects of climate change, where periods of drought will be increasingly frequent, which will affect both rainfed and irrigated crops. Based on this problem, the need to develop water-stress-tolerant crops arises; therefore, several studies consider the estimation of drought indices as tools to select genotypes tolerant to water deficit. This study aimed to evaluate six drought indices in 15 crystalline wheat genotypes under two irrigation depths in two localities in Coahuila and Nuevo León during the autumn-winter 2023-2024 agricultural cycle. The evaluated treatments were two irrigation depths for each locality: IR1 of 37.27 cm and IR2 of 20.92 cm for Zaragoza, Coahuila, and IR1 of 42.24 cm and IR2 of 19.35 cm for Navidad, Nuevo León. The experimental design consisted of randomized complete blocks arranged in split plots with two replications. The water stress tolerance index was the one that best related to grain yield under water-deficit conditions for Zaragoza, Coahuila. The tolerance index was the one that was best associated with grain yield under water-stress conditions for Navidad, Nuevo León. 715 and 738 were the most tolerant to water stress in both localities.

Antagonistic microorganisms as management of Fusarium oxysporum wilt of blackberry
type: item
description: In the states of Michoacán, Mexico and California, USA, blackberry (Rubus sp.) production is affected by wilt, which causes the loss of thousands of hectares. In the present work, the causative agent of the disease was identified and control alternatives with antagonistic microorganisms were proposed. In 2022, the causative agent of the disease was isolated and morphologically identified from an orchard in Tocumbo, Michoacán. A preliminary laboratory bioassay was performed with strains of B. subtilis, B. amyloliquefaciens, P. fluorescens, and Trichoderma spp., native to Tacámbaro and Taretan, Mich. The outstanding strains were tested in a greenhouse on plants of blackberry cv Tupy as a preventive measure and as a control, under an experimental design of randomized blocks with six repetitions. In the preliminary tests, all the strains used showed an inhibition of the mycelial growth of the pathogen greater than 50%, with Trichoderma sp. from Tacámbaro, B. subtilis and P. fluorescens standing out. In the tests carried out in situ, preventively applied treatments decreased the incidence of wilt by 57% to 66%. In terms of severity and plant height, Trichoderma sp. stood out, while the percentage of root necrosis decreased by 56% to 70% with all treatments. Control treatments also showed antagonistic efficacy, although to a lesser extent, they decreased the incidence of wilt by 2 to 58% and the percentages of root necrosis by 19 to 62%. Antagonistic microorganisms can be incorporated as a comprehensive management strategy with high efficiency.

Phytoparasitic nematodes in broad bean crops in eastern Puebla
type: item
description: The broad bean is one of the most important crops in the Central Mexican Plateau due to its adaptation to edaphoclimatic conditions and its high nutritional value in the diet of the inhabitants of this region. Nonetheless, the yields obtained are low compared to the world average. Phytoparasitic nematodes are one of the main constraints to broad bean production in other parts of the world; however, its presence in this crop is unknown in Mexico. In this work, phytoparasitic nematodes associated with broad bean crops were identified and quantified in 10 farms in the municipalities of Tepeyahualco and Cuyoaco, Puebla, and in plants germinated in sterile soil from seeds from different areas in 2022. The following six genera of phytoparasitic nematodes were found: Criconemoides, Ditylenchus, Helicotylenchus, Hoplolaimus, Pratylenchus and Zygotylenchus. The most abundant genera were Ditylenchus and Pratylenchus, with a population density of 11 and 7 specimens per 100 cm3 of soil and 159 and 60 specimens per 100 g of plant tissue, respectively, and they were found in all sampling sites. The population density of Ditylenchus exceeds the economic threshold of the crop; in addition, specimens of this genus were found in plants germinated in sterile soil. The results show that Ditylenchus is distributed throughout the sampled area and can affect yield. Further studies are needed to determine the identity of nematode species and their distribution in other production areas.

Yield, biomass and phenology of the cross between wild and domesticated beans
type: item
description: Hybridization makes it possible to improve beans (Phaseolus vulgaris L.). Lines with a broad genetic base are an advantage for obtaining new varieties. P. vulgaris in Mexico, like corn, is one of the staple crops that fulfills various food functions and is subject to constant improvement. The present study aimed to evaluate the progeny or lines obtained from the cross between a wild and a domesticated parent, grown in greenhouses and hydroponics to determine seed yield, biomass production, and their phenology. The study was carried out in 2019 at the Montecillo Campus, College of Postgraduates. The assessment included wild beans (S13), domesticated beans, registered as Negro Tacaná, and five lines (53b, 51b, 118b, 111, and 3.3) product of the cross of S13 with Negro Tacaná. Each parent and each line was considered as a treatment and were distributed in a completely randomized design. Lines 118b and 3.3 produced the highest seed yields, 225.3 g plant-1on average; the wild parent, the domesticated one, and lines 11.1 and 51b intermediate yields (150.5 g plant-1), and line 53b the lowest yield 98.6 g plant-1. The S13 parent had the highest number of seeds per pod and weight of one hundred seeds, whereas this was the opposite in Negro Tacaná. The yield and time to occurrence of the phenological stages was a response to the environment and the management of the crop, which allowed the maximum expression of its genetic potential.

Behavior of hybrids, improved varieties and native varieties of yellow corn in Chiapas
type: item
description: In 2016, Mexico imported almost 13 million tons of yellow corn, valued at more than 2.3 billion dollars. However, imports could be reduced or eliminated if the yellow-grained varieties and hybrids generated by the National Institute of Forestry, Agricultural and Livestock Research were grown. The study aimed to identify the best hybrid and the best variety of yellow corn that the National Institute of Forestry, Agricultural and Livestock Research has released for the Mexican tropics, where more than 420 000 ha are planted, and 2.1 million tons of yellow corn are produced. During the spring-summer agricultural cycle of 2018, 21 genotypes were evaluated in three localities in Chiapas; the hybrids H-443A, REMACO15A and H-386A stood out statistically with grain yields of 5.748, 5.608, and 5.514 t ha-1 and equaled two of the control commercial hybrids; of the improved varieties, Población Amarilla C1 stood out with 4.9 t ha-1 and of the native varieties, the Olotillo Amarillo-1 variety, from Ocozocoautla, stood out with 3.1 t ha-1.

Sustainable production systems strategies in the Mixteca Alta region of Oaxaca
type: item
description: In Mexico, the problems faced by rural communities lie in their high institutional economic dependence. The integration and participation of producers and society represent an opportunity to use natural resources sustainably. The objective was to describe proposals for sustainable production practices as possibilities for producers in the rural communities of Chalcatongo de Hidalgo to apply in the management of productive projects and in the improvement of the local economy. Forests have the capacity to capture carbon dioxide (CO2), which is traded in exchange for economic resources. Nevertheless, it is required to have a solid organization, strong commitment, constant effort and effective collaboration of social capital. After a review of relevant documents, database analysis, and participant observation, it was determined that it is feasible to apply sustainable productive practices to the management of sustainable projects and local economies; however, commitment, awareness, responsibility and the implementation and strengthening of social capital are essential.

Microbial contamination during stages of in vitro propagation of Agave angustifolia Haw.
type: item
description: When Agave angustifolia stem tissues are established in vitro, microbial contamination frequently occurs; therefore, the use of antibiotics to solve this problem was evaluated. The purpose of this work was to determine the percentage of stem tissues that had an aseptic establishment and exhibited morphogenetic response in three situations: 1) during in vitro establishment (stage I); 2) in explants in which organogenesis with shoot formation occurred in stage I but were contaminated with bacteria, and these were treated with antibiotics to eliminate contamination; and 3) in aseptic adventitious shoots obtained in stage I and transferred to propagule multiplication medium (stage II). The percentages of aseptic cultures, viable tissues, and organogenic response were evaluated. The results showed that only between 3.68 and 8.73% of stem tissues were aseptic during stage I. However, by applying antibiotics to shoots already formed but contaminated with bacteria at this stage, asepsis was recovered in 52.5% of the cultures. On the other hand, adventitious shoots that were aseptic from stage I and transferred to the multiplication medium (stage II) maintained asepsis at 89.88%; all were viable and showed formation of new shoots. These results indicate that antibiotic treatment in already induced stem tissues is an effective strategy to rescue contaminated cultures, and that transferring aseptic shoots to the multiplication stage allows maintaining aseptic cultures with morphogenetic response.

Alternative agroforestry for improving the semi-arid climate of Salamanca
type: item
description: The research was conducted during 2022 and 2023 in the northern region of the municipality of Salamanca, Guanajuato, in the localities (Los Hernández, Los Razos de Ancón, Los Cenizos and La Compañía) corresponding to the semi-arid zone, where production systems are highly vulnerable to accidents, mainly due to water scarcity. In order to know their complexity and propose alternatives for improvement, a diagnosis of the production systems was carried out. The methodology used was the agrarian diagnosis, and the tools employed to obtain the information were semi-structured interviews, geographic information systems, and the 2020 Population and Housing Census. The results showed three principal agroecosystems: irrigated agriculture (agricultural), rainfed agriculture (agrosilvopastoral), and rangeland (silvopastoral), as well as 10 cultivation or rearing systems. In order to understand their complexity and propose alternatives for improvement, a typology of production units was developed, identifying three categories that were very similar to one another yet distinct. To determine economic indicators, the methodology generated by Dufumier (1996) and Apollin and Eberhart (1999) was used, which aims to understand the functioning of production systems and their prospects of evolution. It was concluded that the stability and permanence of production units depend on the ways of using available resources, whereas their differentiation is a function of the availability of water, the degree of intensification of labor, the available surface area, and the use of technology.

Determination of sample size in polyembryonic citrus seeds using robust methods
type: item
description: The percentage of polyembryonic seeds and the number of embryos per seed (NE) are variables commonly used to estimate the degree of polyembryony in citrus, a characteristic used as an indicator of clonal or vegetative propagation of selected genotypes. However, many studies omit the description of the methods used to determine the appropriate sample size in the quantification of these variables. The purpose of this work was to propose a robust statistical methodology for calculating the optimal sample size in polyembryonic studies in citrus using the maximum distance method and the F-test. Five citrus genotypes (C-35 citrange, Volkamer lemon, Amblicarpa mandarin, Valencia orange and Mineola tangelo) were evaluated over two harvest cycles (2020 and 2021) by counting the number of embryos in 100 seeds per genotype. Since the variable of the number of embryos per seed was not normally distributed, the maximum distance method was applied using coefficients of variation calculated with the winsorized mean and a nonparametric bootstrap procedure. The results indicated optimal sample sizes of 26 to 28 seeds, with coefficients of variation of 6% to 11%, depending on the genotype. It was concluded that, for the genotypes evaluated, analyzing samples of up to 50 seeds is sufficient to estimate the degree of polyembryony accurately.

Characterization and phenological prediction of tropical black bean genotypes
type: item
description: The phenological characterization of black bean varieties generated by the Bean Program of the National Institute of Forestry, Agricultural and Livestock Research for southeastern Mexico is conducted by quantifying the number of days after sowing required to reach the different stages of development. This characterization is imprecise for contrasting environments. This study aimed to characterize nine advanced lines and two varieties of opaque black beans by using the number of days after sowing and the index of growing degree-days necessary to achieve the stages of flowering and physiological maturity and to compare the accuracy of the number of days after sowing and the growing degree-days to predict phenology. The number of days after sowing and the growing degree-days required by the genotypes to reach the flowering and physiological maturity stages were quantified across nine environments in southeastern Mexico. The ability of five mixed models was evaluated, considering the number of days after sowing, growing degree-days and environment as fixed effects and genotype as a random effect, to predict the phenological stages of the lines and varieties. Four lines were earlier than Negro Grijalva (1 892 growing degree-days), with an average of 1 859 growing degree-days; in contrast, four others obtained an average of 1 902 growing degree-days, higher than Negro Grijalva but lower than Negro Comapa (1 920 growing degree-days) and only one line was later than both varieties (1 976 growing degree-days). The best model for predicting phenology was the one that considered only the growing degree-days, regardless of the environment. It was concluded that growing degree-days are more accurate than the number of days after sowing for predicting the flowering and physiological maturity of the genotypes in the different evaluation environments.

Influence of Sargassum spp. extract on germination and antioxidant activity of tomato seedlings
type: item
description: In recent years, the macroalga Sargassum spp. has become an economic and environmental problem in several coastal regions. Nonetheless, due to the wide variety of bioactive compounds it possesses, it has been proposed as a sustainable alternative in agriculture, as it can improve seed germination, nutrient absorption, and photosynthesis, and mitigate biotic and abiotic stress. The objective of this study was to evaluate the effect of priming tomato seeds with aqueous extracts of Sargassum spp. on germination, vigor, biomass, photosynthetic pigments and some indicators of the antioxidant system of seedlings. The concentrations of the extracts were: 0.5, 1.5, 2.5 and 3.5%, and a control with distilled water. The results indicate that the extracts improved germination, vigor, phenolic compounds, flavonoids, antioxidant capacity and photosynthetic pigments. There were no significant improvements in biomass. These results suggest that applying Sargassum spp. extracts may be an ecological alternative to improve germination parameters and stimulate the synthesis of secondary metabolites in tomato seedlings.

Bibliometric analysis of artisanal textile clothing
type: item
description: Studies on artisanal textile clothing (ATC) contribute to preserving this productive activity; this study aimed to conduct a bibliometric analysis on the topic of ATC using the Scopus digital library through the construction of an algorithm that allowed selecting documents that have addressed the subject during the last two decades and thus measure the scientific activity and identify the different study approaches from which it has been analyzed; the methodology used was divided into seven stages through which the consulted information was systematized; the metadata imported in CSV format were interpreted using the bibliometrix library of the RStudio program, version 4.4.2; among the main results, it was obtained that the scientific production on ATC in Scopus has increased by 4.7 times in the period analyzed, mostly under historical, anthropological and archaeological orientations, among others and with greater productivity within the Asian continent; likewise, greater connectivity was observed through the set of metadata via the term ‘traditional’ located in the abstract section; however, it is believed that within this segment of scientific production, it is necessary to develop research that addresses the current contexts on the ATC production, such as the value chain approach.
