Effect of Dark Treatment on Physiology of Pot Phalaenopsis

Abstract

本試驗以蝴蝶蘭 Phalaenopsis New Candy 'KHM293'為試驗材料，探討暗處理對不同花序成熟度的蝴蝶蘭植株外觀品質和生理變化之影響，以期確定適合長程暗貯運的植株條件。試驗中以花序開放成熟度較高的植株，對長時間的暗逆境有較佳的耐受性，包括有花朵萎凋率與乙烯生成量較低，葉綠素含量變化幅度較小。This experiment used Phalaenopsis New Candy 'KHM293' for experiment the material, study the effect of dark treatment on appearance quality and physiological change of the Phalaenopsis has different of the mature degree of inflorescence, to expect confirmed plant condition that suit the dark transport of the long distance. Plants with higher maturity of flower clusters had the better endurance to the dark stress of the long time including the lower flower wilting rate and ethylene production, and the chlorophyll content variety range was smaller
