Effects of Post Harvesting On Biochemical Changes in Gladiolus Cut Flowers Cultivars (White prosperity)

Abstract

4 Abstract: Cytokine and gibberellic acid have been reported in several studies to improve the postharvest vase life of many cut flowers. Foliar application of nutrients and plant growth regulators may improve flower quality parameters. In this study the postharvest behavior of Gladiolus was studied on White Prosperity cultivars to increase longevity of cut flowers. Primarily bulbs were treated with four different concentrations of benzyladenine (0, 100, 150, 200 mg/l) and gibberellic acid (GA ) (0, 50, 100, 150mg/l) solely for 6 hours then 3 planted. After 1, 5 and 10 days after harvest. Evaluations of carbohydrate, protein and chlorophyll content in the leaf and petals were done. The results showed that the soluble sugar content increased in both of the petals and leaves in 5 day after harvest. Soluble sugars content in leaves were higher than the petals in 5 day after th th
