摘要: 用生理生化的方法从低温半致死温度、自由水、束缚水含量、渗透调节物质含量及内源激素含量等生理指标研究了不同光强对曼地亚红豆杉(Taxus media cv. Hicksii)抗寒性的影响,各项所得结果趋于一致,确定了曼地亚红豆杉抗寒性的大小顺序为:自然光、一层遮荫、二层遮荫。同时也表明将这几项指标结合起来评定植物的抗寒性大小效果较好。

关键词: 曼地亚红豆杉, 光强, 抗寒性, 生理指标

Abstract: The influence of different light intensity on the leaf cold resistance abilities of Taxus media cv.Hicksii was studied by the method of physiology biochemistry from the follow physiologic indexes:the semilethal low temperature (LT50), the contents of free water and bound water, osmoregulation matter and endogenous hormone. The results showed consistent, the leaf cold resistance abilities were ascertained from big to small as follows:natural light; one-layer shade; two-layer shade. It also indicated that it was better to evaluate the leaf cold resistance abilities by combining the several indexes.

Key words: Taxus media cv.Hicksii, light intensity, cold resistance, physiologic index
