Influence of preservative solution treatments and packaging types on post harvesting of lilium storage under exogenous ethylene.

Received: Revised: Accepted: June 13, 2014 July 24, 2014 August 14, 2014 Lilies are among export flower crops which maintaining the freshness and extending the vase life of cut plants are very important to the success of their exports quality. During post harvesting period maintaining physiological functions of cut flowers vary actively even after harvest and the beginning of their senescence very often found depends on ethylene. The uses of preservative solutions are considered a common practice for the storage of floral stems. These treatments allow to control ethylene synthesis, pathogen development, maintenance of hydric and respiration balance, and latter to complete their development. The research project was conducted to study the vase life of cut lilium flower with preservative materials used as pulsing solution contain 8-hydroxyquinoline sulphate (8HQS) and silver thiosulfate (STS) under room conditions. We found different factors influenced on vase life of cut lilium flowers which had not show the same efficacy when applied together. STS pre-treatment did not effective under high concentration of exogenous ethylene treatment.
