Research Abstract

In order to improve the postharvest quality and the export ability of cut rose (Rosa hybrida L.) cv. Happy Hour, the effect of silver thiosulphate (STS) as an ethylene inhibitor was investigated. STS was used at 0.2, 0.3, 0.4 and 0.5 mM as pulsing treatment for 6 h while control flower were kept in distilled water. STS treatment significantly extended the vase life and minimized the weight loss compared to the control. STS treatment enhanced the relative water content (RWC) of flowers and significantly retarded the degradation of chlorophyll and carbohydrate contents of cut flowers during vase life evaluation. The ethylene production by rose cut flowers was significantly decreased by applying STS treatment. The treatment of STS at 0.4 mM was recommended in order to inhibit the negative effects of ethylene and hence prolong the vase life and maintain the postharvest quality of rose cut flowers. Therefore, STS treatment is advisable during rose transport and handling in areas where the air is commonly contaminated with ethylene.
