摘　　要：调查了江浙地区9个公园的小叶鸡爪槭、红枫及羽毛枫采集地的翅果的6个表型特征,分析品种间及品种内的翅果形态变异、小叶鸡爪槭翅果各性状的相关性,从而探讨鸡爪槭翅果表型变异模式.结果表明,4个翅果表型性状（翅果的长、宽、厚度、百粒重）在品种间差异显著.小叶鸡爪槭的翅果表型性状在采集地间虽未达到显著差异,但是也有较高的变异系数（10.007％-24.758％）;调查的6个性状之间有较高相关性（-0.85 -0.86）.该结果表明,鸡爪槭翅果的形态变异在品种间表现稳定,有一定的遗传稳定性,可以作为品种鉴定的依据.小叶鸡爪槭有较丰富的表型变异,有较好的开发前景.This study gathered the samaras from 9 populations of A.pahnatum var.thunbergii,A.palmatum cv.Atmpurpureum and A.palmatum cv.Dissecrum planted in Jiangsu and Zhejiang provinces.The six characters （the length,width,length-width ratio,thickness,wings angle and 100-seed weight of samara） were surveyed to analyse the phenotypic variation within and among varieties,correlation of phenotypic characters within A.pahnatum var.thunbergii different localities.Results showed the samara of phenotypic characteristics exited significant variation among varieties.There were different extent of variation existed in the phenotypic characteristics of length,width,thickness and the 100-seed weight.Although samara phenotypic characteristics did not reach significant variation,the different localities of A.pahnatum var.thunbergii showed higher coefficient of variation （9.978％ to 24.758％）,also it showed significant relationship among the different phenotypic characteristics （-0.85-0.86）.These results indicated that the samara phenotypic variations are stable among varieties can be used as the marker for cultivar identification.There are abundant phenotypic variations existed in populations of A.pahnatum var.thunbergii,and have a good development prospects.
