摘　　要：对147份云南枇杷野生资源叶片表型性状进行了调查分析,结果表明,这一群体枇杷种质资源的叶姿、叶形、叶片长度、叶片宽度、叶形指数、叶背茸毛、叶面形态、叶片横切面形状、叶面光泽、叶片颜色等性状均存在丰富的多样性。其中,叶背无茸毛的种质占77.62%,初步断定这个群体中的多数种质不是普通枇杷类型。The leaf characters of 147 loquat accessions of wild germplasm resources collected from Yunnan Province as well as their diversity were investigated. The results indicated that there were abundant diversity in leaf attitude, phylliform, leaf length, leaf width, leaf shape index, pubescence of leaf back, shape and luster of leaf surface, shape of cross section and leaf color in these germplasm resources. Among them, the germplasm accessions without pubescence in leaf back accounted for 77.62%. It was preliminarily concluded that most of the germplasm accessions were not belong to Eriobotrya japonica type.
