裸果木叶片的解剖结构与生态适应性
The Leaf blade Anatomical structures and Their Ecological Adaptability of Gymnocarpos przewalskii Maxim.
摘要
Abstract
[ Object ] The basic information of Gymnocarpos przewalskii Maxim. Was provided through the research on the leaf structure characetristics of Gvmnocarpos przewalskiiMaxim. With the adaptable for the grown under arid environment. [ Method ] The leaf anatomy structure of Gymnocarpos przewalskii from two arid environmental conditions was researched by the method of paraffin section. [ Results ] Compare with growing in the environmental condition of better water, the leaf anatomy characteristic of that in arid environmental condition was as follows:① the leaf area of cross section decrease obviosely; ② the thickness of epidermal cells increase obviosely and the thickness of horny layer increase; ③the cells of palisade tissue become more compacter and the percentage of palisade tissue in leaf blade increase a lot; ④ the area of vascular in main vein and it spercentage in leaf blade incease incease a lot in order to its conveying efficient, and the percentage of palisade tissue in leaf increased. [ Conclusion ] The structure characteristics of the Gymnocarpos przewalskiiMaxim. Showde it was with the better adaptability for the arid enviroment.关键词
