Effect of Pulsing Solution and Packaging Type under Exogenous Ethylene on Physiological Characteristics and Post Harvesting Quality of Cut Roses (Rosa hybrida)

2 Abstract: Roses (Rosa hybrida) are belong to the family of Rosaceae which are native to diverse habitats in the Northern hemisphere are the most important ornamental plants. The flowers are marked either as potted plants or cut flowers. Having long lasting life period of cut flowers will effect to their attraction to people for their natural beauty and appearances and help the socio-economic value of flowers remain intact. Thus, this study was initiated to evaluate the effectiveness of pulsing solution, packaging type and ethylene on physiological characteristics of fresh cut roses that effect on their postharvest life and quality. Results show that unlike higher protein content in glass chamber (2.13), the production of ethylene was higher (701.4) compare to polyethylenamid chamber. Therefore, by reducing the dry weight (3.96) and vase life of cut flowers, the glass chamber seems not supportive as polyethylenamid to increase the vase life. A moderate treatment with exogenous ethylene (1-10 µl ) and STS pre-treatment under polyethylenamid coverage was suitable condition 1 for extending the rose vase life longevity, saving their natural appearance and delaying senescence.
