摘要
合理利用野生植物资源,保护珍稀濒危植物,对于发展经济,开展科学研究,改善自然环境,维护生态平衡,丰富人民生活皆具重要作用。因此,近些年来围绕着这些植物的研究日趋繁多,有关报导也屡见不鲜。
In this paper, there are the vegetative organs of nine species of the valuable relic protected plants in Xinjiang had been determined, they are: Ferula sinkiangensis, Haloxylon ammodendron, H. persicum, Ammopip-
tanthus mongolicus, Ao nanus, Glycyrrhiza inflata, G. uralensin, Poacynum pictum and Calligonum ebi-nuricam. The first five species are typical xerophytes, there are a lot of xeromorphic structures in these plants, such as: thick cuticle, hypodermis, well-developed palisade, water-storing tissues with large cells, well-developed fiber, crystal cells and mucilage cells and so on. Although there are also some xeromorphic structures in the last four species of plants, G. inflata and P. pictum are the transitional forms from mesophytes to xerophytes, F. sinkiangensis and G. uralensis only are mesophytes. The fair which is on the surface of the leaves and stems of A. mongolicus and A. nanus is the derivative of cuticle.
