Effect of exogenous ethylene and ethylene inhibitor on flower physiology of cut rose 'Grand Gala' and 'Golden Medal'.

Two cultivars of Rosa hybrid 'Golden Medal' and 'Grand Gala' were tested in this study to investigate the effects of exogenous ethylene and chemical pulse on the flower opening and postharvest life of cut roses. The vase life was extended at pulse treatment with 0.25-2 mM STS and 10 mM AIB to cut roses for 24 h then transfer to distilled water. The flowers' fresh weight daily decline rate was slowed down but the diameter of flower bloom increased. These were negative effects in AOA and CHI-treated, vase life was significantly reduced, and phytotoxicity were observed. Exogenous ethylene for 0.1-2 ppm had promoted flowers opening of cut 'Golden Medal' rose flowers at the initial bloom stage. The fresh weight and vase life decreased along with the increasing concentration of ethylene addition. The data showed that ethylene supposedly played an effective role for 'Golden Medal'. However, exogenous ethylene had little effect on bud opening and longevity were less affected for 'Grand Gala' cut flowers
