摘　　要：为研究太行山地区栓皮栎种源间的遗传变异,为栓皮栎新品种选育提供种质资源,对6个种源栓皮栎种子形态指标(千粒重、种长、种宽、种形指数)、萌发特性(发芽率、发芽势、发芽指数)及当年生苗期生长性状进行分析。结果表明,种子形态指标和萌发特性在不同种源间均存在显著差异,因此栓皮栎良种选育具有很大地潜力。千粒重、种长、种宽、种形指数分别为:2897.53~5402.60 g、19.38~22.69 mm、15.97~19.51 mm、1.14~1.34;发芽率、发芽势、发芽指数、苗高分别为:44.45~91.11%、16.67~45.55%、1.07~2.86、47.49~63.99 cm。利用模糊隶属函数对千粒重、发芽率、发芽势、发芽指数和苗高综合分析,种源种实品质依次为:河南林州>山西夏县>河南修武>天津蓟州>北京海淀>河北易县。In order to study the genetic variation among seed sources and provide germplasm resources for breeding new varieties of Quercus variabilis sinensis in Taihang Mountains,the seed morphological indexes(1000-grain weight,seed length,seed width,seed shape index),germination characteristics(germination rate,germination potential,germination index)and seedling growth traits of 6 seed sources were analyzed.The results showed that there were significant differences in seed morphological indexes and germination characteristics among different provenances,so there was a great potential for the breeding of Quercus variabilis.The 1000 grain weight,seed length,seed width,and seed form index were 2897.53~5402.60 g,19.38~22.69 mm,15.97~19.51 mm and 1.14~1.34;The germination rate,germination potential,germination index and seedling height were 44.45~91.11%,16.67~45.55%,1.07~2.86 and 47.49~63.99 cm.The comprehensive analysis of 1000 grain weight,germination rate,germination potential,germination index and seedling height by using fuzzy membership function shows that:Linzhou in Henan>Xia Xian in Shanxi>Xiuwu in Henan>Jizhou in Tianjin>Haidian in Beijing>Yi Xian in Hebei.
