Abstract: 23 basic types of grass seedling in 291 widely representative species of 83 gnera have been recognized according to the combinations of seedling morphology of underground organs,aboveground organs and the establishmental types of the seedlings.23 basic types were grouped into 4 large types——Type Festucoid,Type Panicoid,Type Eragrostidoid,and Type Bambusoid.The 4 large types funda-mentally conformed to the subfamilies of the systematics of the Grasses (Gramineae) in species.The basic types contained in large types shawed the rele-tionship of subfamilies and their sequence in evolutionary line.

摘要: 本文通过对83属201种禾本科植物幼苗地上器官、地下器官和建植类型的分析将禾本科植物幼苗划为23个基本类型。进一步对禾本科植物的23个幼苗基本类型进行综合归纳,将其归并为四个大类——狐茅类(Festucoid)、黍类(Panicoid)、画眉草类(Eragrostidoid)和竹类(Babusoid)幼苗。这四个大类基本上与系统分类中的亚科相吻合,同时四个大类所包含的基本类型也反映了禾本科各亚科之间的亲缘关系和进化上的次序。
