| Abstract: | The characteristics of leaf laminea of 5 species of salix growing in Qinghai plateau(3800-4500m above the sea level)were anatomically studied.It was shown that all the leaves,which are hificial,consist of 2-3 layers palisade,and are of biepidermis covered with thicker cuticle.We think that it is the resrlt of adaption of plants to the environment in shich they live. |
