摘要
对生长在松嫩草地盐碱生境的五种双子叶植物二色补血草（Ｌｉｍｏｎｉｕｍｂｉｃｏｌｏｒ）Ｏ．Ｋｕｎｔｚｅ、蒙古鹤虱（Ｌａｐｐｕｌａｉｎｔｅｒｍｅｄｉａ）（Ｌｅｄｅｂ．）、碱蒿（Ａｒｔｅｍｉｓｉａａｎｅｔｈｉｆｏｌｉａ）Ｗｅｂｅｒ、伏萎陵芽（Ｐｏｔｅｎｔｉｌｌａｓｕｐｉｎａ）Ｌ．和鹅绒藤（Ｃｙｎａｎｃｈｕｍｃｈｉｎｅｎｓｅ）Ｒ．Ｂｒ．进行了解剖研究。扫描电子显微镜照片表明，它们都具有明显的抗盐碱和抗干旱的结构特征［８］，尤其是它们叶片表面上的附属物，即表皮毛、角质层、蜡质纹饰、表皮毛上的疣状突起和表皮中的花型盐腺等解剖结构，是抗盐碱抗干旱植物的主要特征［９］。
The five xerophytes plants are growing in the plain of the song nen,i.e.Limonium bicolor O.Kuntze.Lappula intermedia (Ledeb.)M.Pop.Artemisia anethifolia Weber.Potentilla supina L.and Cynanchum chinense R.Br.They have been studied on the anatomy under ESM.The result show that all of them have the structure characters in resisting of drought and saline-alkali.The leaves have especially shown that they have the subsidiary thins.Their structure are the epidermis'cuticle.wax grains.the tumid on the epidermis hairs and the flower type of salt Gland,epidermis'which are the plant character of resisting the saline-alkali and the drought.
