温度对中国水仙贮藏期蔗糖含量变化的影响

Effects of Temperature on Sucrose Content in Narcissus tazetta var. Chinensis during Storage Period

[目的]研究温度对中国水仙贮藏期蔗糖含量变化的影响。[方法]以3年生中国水仙品种"金盏银台"为试验材料,分别测定5、15、25、35℃及室温(CK)贮藏条件下内、外鳞片和主芽的蔗糖含量。[结果]贮藏期水仙蔗糖含量基本稳定分布在主芽和内鳞片中,蔗糖运送途径从外鳞片到内鳞片,再到主芽内部;在不同温度处理下,水仙球内的蔗糖含量维持在一定的水平,以供应水仙主芽的形态发育和生长。[结论]该研究对进一步研究水仙贮藏期相关生理生化指标具有重大意义。

[ Objective] To research the effects of temperature on sucrose content in Narcissus tazetta var. Chinensis during stood] With three-year-old N. tazetta as the test materials , the sucrose contents in main buds , innner and outer scatected under the 5 , 15 ,25 ,35 ℃ ad room temperature（ CK） . [ Result] During storage, the sucrose content of N. tazetta was basically distributed in main buds and innner scales. The sucrose transported from outer scZ cs to innner sc a les ,and then to main buds. Under the treatments of differ-ent temperatures,sucrose content in bulb maintained at a certain level,so as to provide the development and growth of the N. tazetta main buds.[Conclusion ] The study is of great significace in researching relevant physiological and biochemical indexes of N tazetta during storage period.
