摘要 除去非胶成分使纯粹的橡胶丝完全暴露出来,可得到杜仲全叶的胶丝网络体系。通过观察和比较,可见杜仲叶中的胶丝网络结构与叶脉的网络结构完全一致,证明胶丝是叶脉的组成部分。同时观察到杜仲叶缘锯齿的骨架主要由两股胶丝组成,胶丝网络的分枝形式为反向汇集型。 A complete network system of pure gutta-percha filaments in the leaves of Eucommia ulmoides was exposed after other components were removed. Both network structures of the filaments and veins were found to be fully consistent, suggesting that the filaments are the composing parts of the veins. It was also observed that the frame of serrated margin was composed mainly of two skeins of gutta-percha filaments. And the branched form in the network converged reversely. Near the leaf apex unbalanced grown serrations ranged in the margin.
