The quality of miniature potted roses during their shelf life is limited by bud abscission and premature flower senescence. Rosa hybrida L. cv. Amore plants were pretreated with silver thiosulphate (STS) at 0.2 and 0.4 mM and with 1-methylcyclopropene (1-MCP) at 0.3, 0.5 and 0.7 g m-3 for 6 h in order to investigate the effects of these chemicals on the postharvest quality. Both chemicals extended the flower longevity as well as the plant display life compared with the untreated control. The best treatments in this respect were STS at 0.4 mM and 1-MCP at 0.5 g-3 for 6 h, which resulted in the least degradation in the chlorophyll content of the leaves. The treatment with STS at 0.4 mM increased the flower longevity and plant display life by 1 and 1.67 days, respectively, compared with the 1-MCP pretreatment at 0.5 g m-3. Since 1-MCP treatment does not have the heavy metal implications of STS treatment, the use of 1-MCP pretreatment for extending the shelf life of miniature potted rose cv. Amore was recommended.

The postharvest quality of miniature pot roses is limited by bud abscission and premature flower senescence. Rosa hybrida `Victory Parade' plants were treated with ethephon to study their sensitivity to ethylene and with silver thiosulfate (STS) to investigate its inhibitory effects on ethylene action. Bud abscission and flower senescence were promoted by spraying plants with ethephon, and the longevity of individual flowers and whole plants was reduced. All STS concentrations (0.4, 0.8, 1.2, 1.6 mM improved postharvest keeping quality. Bud abscission and flower senescence were decreased and the longevity of flowers and whole plants was improved by applying STS. Chemical name used: 2-chloroethylphosphonic acid (ethephon).

Abstract Rose is an ornamental plant, which constitutes one of the leading cut flowers in the world. The vase life of cut Rosa hybrida L. flowers is truly short. We examined the effect of various temperatures and different time duration factors on postharvest longevity, and some other physic-biochemical characteristics and antioxidants activity. Fresh cut Rosa hybrida L. flowers were treated by water with various temperatures (23º, 42º, 47º, and 52°C) and different time duration (5, 10, 15, and 20 min). Maximum vase life (7.52 days) was related to cut flowers that were treated with 52°C for 15 min. Minimum vase life (4.46 days) was observed in cut flowers that were treated with 42°C for 5 min. Treatment of cut flowers by water with the temperature of 52°C for 15 min induced the highest water absorption, petal’s anthocyanin, and leaf’s chlorophyll. The lowest ethylene production was also obtained in cut flowers treated with 52°C for 15 min. The use of warm water (52°C) for 15 min clearly extended the vase life and most traits pertaining to the vase life of cut Rosa hybrida L. flowers.
