| 摘 要： | 通过对花花柴(Karelinia caspica)、甘蒙怪柳(Tamarix austromongolica)、猪毛菜(Salsola collina)、灰绿藜(Chenopodium glaucum)、长芒草(Stipa bungeana)五种盐生植物显微结构观察,这五种盐生植物营养器官的形态结构均呈现一定的适应性特征:⑴ 气孔器下陷,角质层加厚,表皮细胞排列紧密而整齐;⑵多为等面叶,叶片栅栏组织发达,或退化为鳞片状,而具同化枝;⑶茎、叶多为肉质化,贮水组织发达;⑷具有含晶细胞,枝叶具盐腺。

| Abstract: | The results of observation on the microstructure of Karelinia caspica, Tamarix stromongolica, Salsola collina. Cheno Dodium glaucum, stipa bangenana show that the nutritional organs of these halophytes present some adaptability structures as follows: (1) sunken stomas, thick cuticle and orderly arrangement of epidermal cell; (2) equilateral leaves with developed palisade tissue, or squama-shaped leaf; (3) well-developed water-storing tissue in stems and leaves; (4) crystal cells, salt glands in most of the leaves and assimilating branches. |
