文心蘭切花採收後重切及蔗糖、8-hydroxyquinoline sulfate對切花品質之影響

Abstract

文心蘭品種(Oncidium. 'Gower Ramser')切花，採收後重切可延長瓶插壽命， 瓶插液中添加4％或6％蔗糖對延長瓶捕壽命差異顯著，僅使用殺菌劑8- hydroxyquinolinesulfate(8.HQS﹞效果較差，但以4％蔗糖合併50、100、200 mgl□ 8- HQS，則可延長瓶插壽命且增加花莖上小花開放率效果差異顯著。花瓣唇瓣部分之明亮度 表現經由蔗糖及8-HQS之瓶插液可改善，但對紅色度a值或黃色度b值之差異不大。

Oncidium 'Gower Ramsev' for cut flowers were extended vase life through postharvest recut. Moreover, the supplement of 4% or 6% sucrose in preservatives resulted in longer vase life significantly, but 8-HQS caused less effect. Consequently, mixtur
