摘　　要：在相同的种植和管理条件下,对普通枇杷、栎叶枇杷、大瑶山枇杷和南亚枇杷等4个种210份种质资源的8个花序性状多样性进行鉴定,旨在为进一步的分类鉴定、利用研究提供参考依据。结果表明:(1)枇杷属种质资源的花序支轴姿态、花序支轴密度、花序支轴数、花序形状、花序长度、花序宽度、花瓣颜色、花冠直径Shannon-Weaver多样性指数1.352～2.951,存在丰富的多样性。(2)不同来源地的种质资源花序性状多样性水平差异较大,多样性指数最高的为云南(2.108),其次是贵州(1.962)、四川(1.953)、福建(1.900),美国的最低(1.137)。(3)云南、贵州的枇杷种质资源花序长度、宽度显著或极显著地大于其他地区;野生资源的花序长度、花序宽度和花冠直径均极显著地大于地方品种、选育品种。Diversity of eight flower cluster characters（attitude of lateral in relation to peduncle,density and number of lateral peduncles,shape,length,width of flower cluster,petal color and corolla diameter） of 210 loquat germplasm resources（Eriobotrya japonica（Thunb.） Lind1.,Eriobotrya prinoides Rehd. Wils.,Eriobotrya dayaoshanensis Chen.and Eriobotrya bengalensis（Roxb.） Hook.f.） were studied and analyzed under the same planting conditions.The results showed：（1）there was abundant diversity among them.（2）Diversity index of loquat germplasm resources from different sources varied greatly with the highest of 2.108（from Yunnan）,the lowest of 1.137（from America）.（3）Variance analysis showed that flower cluster length of loquat germplasm from Yunnan and Guizhou were significantly longer than others,flower cluster width of loquat germplasm from Yunnan and Guizhou were very significantly wider than others,both length and width of flower cluster of wild loquat germplasm were very significantly bigger than those of cultivated species and wild relatives.
