Effect of sucrose on the floret senescence and vase life of snapdragon 'Manwall'.

Effects of various concentrations of sucrose on the postharvest quality such as fresh weight, vase life, flowering rate, petal pH, petal colour, and ion leakage of the florets of snapdragon (Antirrhinum majus) cv. Manwall were investigated. In the 0-, 12-, 24- or 48-h pulsing of sucrose as a pretreatment, fresh weight without sucrose (control) decreased rapidly, while that of sucrose increased slowly until the experiments were terminated. Sucrose was found apparently to be effective in increasing the fresh weight when the duration of pretreatment increased. It was shown that sucrose in the vase solution extended vase life and increased flowering rate than the control. Compared to the control, sucrose in the vase solution increased petal pH and consequently, petal colour became brown. When sucrose level was high, petal pH decreased and petal colour was maintained close to yellow. Florets at 7 days became wilted in sucrose above 9%. Floret colour with more + in L and b or - value in a indicated closing to original colour "yellow" in snapdragon Manwall F1. The change of petal colour was reduced at sucrose above 6%. Floret opening was realized at the point to be increased in percent of ion leakage. In pretreatment for 24 h, reduction of ion leakage was found in the treatments except at 6 and 9% of sucrose.
