Abstract: (516 Views)
In order to evaluate the pre-harvest application of calcium silicate and calcium chelate effects on some morpho-physiological characteristics of ‘Dolce Vita’ cut rose in the post-harvest stage, a factorial study was conducted based on a completely randomized design with 3 replications under hydroponic cultivation in a commercial greenhouse. Application of calcium silicate at concentrations of 100, 100, 200 and 400 mg.L-1 and calcium chelate at concentrations of 0, 25, 50 and 100 mg.L-1 in the pre-harvest stage was done by foliar spraying once a week for a month. In this study, morphological (fresh and dry weight of shoots) and physiological indices (chlorophyll a and b, leaves and petals flavonoids, total soluble sugar contents and calcium, silicon and potassium contents of leaves) were measured. The results showed that the application of 100 mg/l of calcium chelate and 200 mg/l of calcium silicate increased the fresh weight and dry weight of flowers (by 2.88 and 3.09 times, respectively), chlorophyll a content (91.85 percent), and the amount of soluble sugar in leaves and petals (2.27 and 1.5 times, respectively) compared to the control. The application of calcium chelate and calcium silicate at concentrations of 400 mg.L-1 and 100 mg.L-1 respectively, caused the highest amount of chlorophyll b (95.9 mg.g-1 of fresh weight) and the longest vase life (6.33 days increase compared to the control). The highest amount of petal flavonoid (1.02 mg.g-1 of fresh weight) was recorded in the concentrations of 100 mg.L-1 of calcium chelate and 200 mg.L-1 of calcium silicate, which was not significantly different from the other treatments except the control. Leaf calcium content was only affected by 100 mg.L-1 calcium chelate (53.84% increase compared to the control). The highest concentration of leaf potassium in the treatment of 100 mg.L-1 of calcium silicate and 25 mg.L-1 of calcium chelate (75.23% increase) and the highest concentration of leaf silicon in the treatment of 200 mg.L-1 calcium silicate and 50 mg.L-1 of calcium chelate (an increase of 1.03-fold compared to the control) were recorded. The results showed that the application of calcium chelate and calcium silicate at concentrations of 100 mg.L-1 and 200 mg.L-1, respectively, were more effective in improving the postharvest properties of rose cut flowers. In general, it can be stated that the combined application of calcium silicate and calcium chelate in the pre-harvest stage could improve the postharvest quality of ‘Dolce Vita’ rose flowers.
