Improvement of postharvest life in several cut flowers by the addition of sucrose.

Sugars play important roles in the keeping quality of cut flowers because the amount of sugar contained in cut flowers is limited. Effects of sucrose treatment on the vase life of several cut flowers were investigated. Continuous treatment with sucrose (100 g/litre) markedly promoted floret opening and extended the vase life of cut sweet pea (Lathyrus odoratus) flowers; pulsed treatment with sucrose was also fairly effective in improving the vase life of these flowers. Hence, sucrose treatment can avoid the use of the pollutant silver thiosulfate. Continuous treatment with sucrose (20 g/litre plus 200 mg 8-hydroxyquinoline/litre) increased the anthocyanin concentrations in petals and extended the vase life of cut flowers from several cultivars of Eustoma grandiflorum. This treatment (optimum 50 g sucrose/litre) was also effective in improving the vase life of cut flowers of snapdragon (Antirrhinum majus). Although pulsed treatment with sucrose (20 g/litre) was fairly effective at promoting flore

t opening in cut hybrid Limonium cv. Blue fantasia 100 (L. bellidifolia x L. latifolium), it hardly improved the vase life; pulsed treatment with sucrose in combination with 10 mM alpha -aminoisobutyric acid (AIB), an ethylene biosynthesis inhibitor, markedly extended the vase life. The role of the application of sucrose to cut flowers is reviewed and discussed.
