摘要
本文对沙柳 (Aalix psammophila Wang et yang)的茎、叶结构做了较为全面、系统的观察比较。得到如下结果 :沙柳的叶为典型的旱生结构 ,茎、叶的维管束发达 ;沙柳雌雄株的茎叶结构差异较明显。从解剖结构看 ,雄株抗旱性优于雌株。
The structure of stems and leaves of Salix psummophila was studied comprehensively.The results showed that the structure of stem and leaf of Salix psammophila had the typical xerophytic feature.The differences of structure of stem and leaf between male and female plants of Salix psammophila are distinguishable. The vascular buudle of male plants stem is more developed than that of female plants stem.These means that the drought resistance of male plants is superior to that of female plants.
