摘要
本文初步研究了骆驼刺、盐豆木和胡杨的叶、以及野胡麻和沙拐枣同化枝的解剖构造。它们显著的旱生构造是:表皮细胞壁加厚,有厚的角质层;同化组织均发育成栅栏组织,栅栏细胞内叶绿体丰富;在薄壁组织中有粘液细胞;贮水组织和机械组织发达。
In the present paper, the anatomical strcture of leaves of Alhagi pseudalhagi Desv, Halimod- endron holodendron (Pall) Voss. and Populus diversifolia Schrenk, and assimilating branches of Dodartia orientalis L. and Calligonum mongolicum Turcz. has been studied. Their anatomical structure has destinet xeromorphic characters. The cell walls of epidermis have thickened and cov- ered with thickness cuticle. Assimilating tissues all develop to palisade layvers, in which contaning abundant chloroplasts. They possess a large number of mucilage cells in parenchyma, well devel- oped water storage tissue and mechanical tissue.
