摘　　要：在本文中利用解剖学方法,对满天星试管正常苗和玻璃苗叶片解剖结构进行了观察比较,结果表明:二者的表皮均由单层细胞构成,气孔突出,叶肉组织无细胞的分化,是等面叶,且叶肉中通气组织发达。与试管正常苗相比,玻璃苗的叶片厚,气孔突出明显,表皮细胞、叶肉细胞体积膨大,有的叶肉细胞的细胞壁发育不全,在某些区域出现空洞,壁的形态呈现不完整的现象。玻璃苗叶片的维管组织呈现退化的状态。By the way of anatomical method,Anatomical structure of leaves of the formal shoots and vitrification shoots were observed and compared,1t was found that both of them were single layer of epidermis,stoma emergented,mesopyll cells were not differentiation,belonged to isolateral leaf and aerenchyma was flourishing in mesopy ll Compare with the formal shoots,the leaves of vitrification shoots were thick,size of mesopyll cells and epidermis cells expanded,cell walls were agenesls of some mesopyll cells and emerged void space in some regionalVascular tissue energed extreme degeneration state of leaves of vitrification shoots'leaves
