Abstract

The present investigation was carried out in a greenhouse, with rhizomes of Alstroemeria cultivar ‘Olga’ under hydroponic system, with universal Steiner solution until harvest. It consisted of two stages: greenhouse phase and vase life. In the greenhouse, foliar fertilization was applied to the crop under a completely randomized experimental design with five replications. Eight doses of Ca(NO3)2, MgSO4- and FeEDTA fertilization were evaluated. The variables evaluated were chlorophyll, leaf length, stem diameter, number of leaves per stem, and stem length. In vase life it was carried out in September 2013. As a preservative solution, two concentrations of the universal Steiner solution were evaluated. Tap water, Chrysal Clear® commercial preservative solution, was used as a control. The experimental unit was a flower stem. The variables evaluated were chlorophyll, fresh biomass, indirect transpiration, total chlorophyll by the AOAC method, days in vase and flower opening. At 0, 2, 4, 6, 8 and 10 days after the cut. In the greenhouse phase, the length of stems, number of leaves per stem and length of leaves, was independent of the dose and frequency of application of foliar fertilizers. SPAD readings, the treatment that showed effect from the first evaluation was 5 with foliar application of Ca(NO3)2 2 g L-1, being different from the rest of the treatments. The stem diameter increased with the application, every 15 days of Ca(NO3)2 1 g L-1 via foliar. In the vase life, the SPAD and total chlorophyll readings of treatments five and six showed higher values. It is possible to maintain the flower stems with a foliar fertilization of Ca(NO3)2 2 g L-1 whose effect in post-harvest was different from that of the other treatments in relation to chlorophyll. This dose applied in pre-harvest plus the addition of a preservative product in post-harvest is important in preserving the green color of the leaves.
