Özet

The postharvest life of cut Eustoma grandiflorum flowers is limited by poor bud opening and bent neck in open flowers. Vase solutions containing up to 6% sucrose or glucose improved the quality and vase life of the flowers. The additional carbohydrate improved petal color, increased bud opening, strengthened pedicels, and extended overall inflorescence longevity by up to 8 days. The principal sugar in the petals of open flowers was glucose, with lower concentrations of sucrose and fructose. Presence of sugar in the vase solution greatly increased the concentration of sugars in the perianth of buds and open flowers. Eustoma flowers are affected by exposure to ethylene and pre-treatment with 1-MCP or STS delays final senescence of flowers that have been held in solutions containing sugar.
