摘　　要：本文对广布于荒漠区的13种蒺藜科植物叶的解剖结构进行了观察比较,结果表明:蒺藜科植物叶均具有典型的旱生结构特征,表现为:叶型小,多肉质化;角质层较发达;气孔下陷;叶肉环栅型,栅栏组织发达,海绵组织特化为贮水组织;输导组织发达。不同属间对环境表现出特有的适应途径,反映了植物对干旱环境的适应多样性。Anotomical characterisitics of plant leaf structure of 13 species of Zypophyllacdae in desert area were observed and compaired,the result showed that the xeromorphic characterisitics of Zypophyllacdae plant were obvious.Small leaf area;the cuticles were developed;stomata were a litter sunken;well develpoed palisade tissue,the spongy parenchyma specicalied as storage organization;well developed conducting tissue.The different species showed their own special adjust method to the different environment,indicat...
