Abstract
Summary Variations in the way of flower opening and vase life of cut rose (Rosa hybrida L.) flowers among 25 cultivars were investigated. The way of flower opening varied among 25 cultivars; the cut flowers of some cultivars did not open completely. The vase life markedly varied among the cultivars; it was the shortest in ‘Bridal Pink’ (3.8 days) and the longest in ‘Calibra’ (14.5 days). To elucidate the factors that affect the variation in the vase life of cut roses with the cultivar, 10 major cultivars in Japan, were used. There was no correlation between vase life and petal thickness or transpiration rate of the cut flowers. To investigate whether vascular occlusion or sugar content is involved in the variation of the vase life, we continuously treated the cut flowers with 200 mg·liter −1 8-hydroxyquinoline sulfate (HQS) on 20g·liter −1 sucrose with both of them. Treatment with HQS, sucrose and sucrose plus HQS significantly extended the vase life of two, two and four cultivars, respectively. However, none of the chemicals extended the vase life of ‘Delilah’, ‘Calibra’, ‘Konfetti’, ‘Pareo 90 ’ and ‘Rote Rose’. The vase life of these cultivars except for ‘Rote Rose’ was longer than 8 days. These results also suggest that a short vase life in some cultivars is attributed to vascular occlusion and/or shortage of sugars.
