新疆10种旱生、盐生植物的解剖学研究

Anatomical Studies On Ten Xerophytes and Halophytes in Xinjiang

对新疆１０种旱生、盐生植物的解剖结构进行了观察和研究，结果表明：这些植物具有典型的旱生、盐生结构，其基本特征为：叶表面有表皮毛、腺毛、角质层加厚、气孔下陷或叶退化为鳞片状．光合作用全部或部分为同化枝代替；叶内部栅栏组织发达，海绵组织退化；叶肉细胞存在有粘液细胞和晶细胞．在茎和同化枝中，皮层细胞加厚，内有贮水薄壁组织，维管束发达．

In this paper we have observed and studied ten xerophytes and halophytes about their anatomical structure in Xinjiang.The results show that these plants have typical xeromorphic and halomorphic structure.The basic tracts are:On the surface of leavs ,there are epidermal hairs,glandular hairs,thick cuticle and sunken stomata;Some Leaves have been reduced to scale formed,and assimilating branchestak place of its function to carry out photosynthesis;The leaves have Well developed palisade tissues and reduced spongy tissues;Mucilage cells and crystal cells lie in the mesophyllous tissue;There are thicker cortex cells,developed vascular bundles and water storing parenchyma cells in stem and assimilating branch.
