摘要
通过解剖几种中藏医用药的高山植物,揭示其对高山低氧环境的适应途径。这对研究青海植物区系、演化具有理论与实践意义。研究的几种药用植物均属中生植物,它们适应高山低氧等环境普遍形成发达的通气组织、机械组织,在叶片中常有数层栅栏组织细胞,构成了高山植物独特的结构特征。
We have anatomied 10 species of alpine plants of Chinese and tibetan medicine, Which is very significant for Qinghai plant flora and their evolution not only in the theory but also in practice. It was observed that aerenochyma and mechanical tissue of alpine plants in Qinghai plateau had been developing, and palisade tissue in their leaves had been developing, too. The adaptive ways and means of plants to the severe lack of oxygen and cold climate of plateau are discussed.
