Cucumis sativus L, biopriming, biostimulationAbstract
The use of beneficial microorganisms in agriculture, such as bacteria, is a practice that allows improving the production of agricultural crops since they can act as stimulants, biofertilizers, and as antagonistic organisms against pathogens. The study aimed to assess seed priming and drench in cucumber with beneficial bacteria on the yield and synthesis of bioactive compounds of the fruits. The bacteria used were Pseudomonas paralactis, Sinorhizobium meliloti, and Acinetobacter radioresistens; in addition to this, a control with distilled water was used. The results indicate that the strains used improved the growth and accumulation of plant biomass compared to the control, which was reflected in a greater length, diameter, and yield of the cucumber fruit, with A. radioresistens increasing the yield to a greater extent compared to the control (37.78%). As for the bioactive compounds (total phenols, flavonoids, and ascorbic acid), antioxidant capacity, and proteins, the bacterial strains improved them substantially compared to the control, which showed the lowest values. These results confirm that the application of bacteria is a promising alternative to improve the production and quality of agricultural crops in a sustainable way.
