Abstract

  Experiments were conducted to study the effects of temperature and chemical treatments on the vase life of cut Asiatic hybrid lily cultivar Pisa, with sixteen chemical treatments using factorial design with 3 replication arrangements. Lilium cut flowers were harvested when the first flower colored fully. Following chemical treatments, they were grouped in different combinations before storage. The treatments included sucrose, 8- hydroxy quinoline sulfate (HQS), citric acid (CA), gibberellic acid (GA3), kinetine (KI) and distilled water as control. Lilium cut flowers were pulsed for 24 hours in different solutions, then brought out and kept in the distilled water at temperatures of 4°C and 22 ° C .Effects of applied treatments were evaluated on different characteristics like vase life, the amount of water absorbed, flower diameter, total soluble solids and fresh weight. Results showed that the temperature of 4°C had the most effect on vase life, keeping the quality of lilium cut flowers. The results also displayed that the chemical treatments kinetine + sucrose had the most effect on vase life and percentage of sucrose, gibberellic acid + kinetine delayed yellowing of the foliage, 8- hydroxy quinoline absorbed the most amount of water, and treatments sucrose + kinetine , gibberellic acid + 8- hydroxy quinoline sulfate and gibberellic acid + citric acid were most effective in increasing the flowers diameter.

Abstract

Leaf chlorosis during both green house forcing and postharvest have been a long standing problem in Easter liliy. The symptoms typically start in the basal leaves and moves progressively upward and reduce flower quality and economic value of crop. In order to delay leaf chlorosis and increase vase life, an experiment was carried out on Asiatic hybrid Lilium cv Canova to study different treatments of benzyladenine (BA) and silver thiosulphate (STS) on pre and postharvest attributs, respectively. The results showed that preharvest application of BA effect the chlorophyll content of leaves significantly, but itُ s effect on stem and pedicle length and harvest time were not significant. Treatment of 0.44 mM BA on increased chlorophyll content greater than another treatments. In postharvest study, factors of 0.44 mM BA on chlorophyl1 content of leaves and leaf longevity, treatment of 0.88mM BA+ 0.6 mM STS on vase life, total soluble solids and uptake solution had most effect. The results showed that application of STS and BA can be used to prolong vase life, delay leaf senescence and enhance postharvest quality of lilium cut flowers during their transport market.
