摘要: 利用扫描电镜技术研究了女菀、矶松、角碱蓬、鹅绒藤、蒙古鹤虱、伏萎陵菜和碱蒿7种耐盐碱植物结构.结果表明,7种植物根中具有发达的通气结构,具有耐盐碱、抗干旱的结构特征,尤其是叶表附属物(表皮毛、角质层、蜡质纹饰)均呈抗逆境结构.

Abstract: Scanning electron microscopic studies on the structure of 7 saline-alkali tolerant dicotyls,Suaeda corniculata,Cynanchum chinense,Lappula intermedia, Potentilla supina and Artemisia anethifolia show that their roots have well-developed aerenchyma, and have the structural characters of saline-alkali and drought-tolerant.The subsidiaries on their leaf Surface such as epidermal hair,cuticle and waxy decorative patterns also show the stressreslstant structures.

Key words: Dicotyls, Structural characters, Grassland, carbon carrying capacity, ecological compensation criterion, carbon footprint
