| 摘 要： | 测定了乌桕不同种源间种子性状的地理变异情况。结果表明：乌桕不同种源间种子带蜡和去蜡百粒质量均呈极显著差异。有7个种源的种子外形大,带蜡百粒质量在14 g以上,为大粒型;有3个种源的种子较小,带蜡百粒质量在10 g以下,为小粒型;其余种源种子为中粒型,带蜡百粒质量为10～14 g。湖南新宁、江西上饶、湖北房县、浙江宁海4个种源种子去蜡百粒质量在所有种源中最大（〉10 g）,带蜡百粒质量也很高,为大粒果用乌桕良种选育的种源材料;贵州龙里、开阳、道真,四川广元,湖北房县,江西新建、于都、上饶,广东阳春9个种源净籽率较高（75%～90%）,为梓油果用良种选育的种源材料;浙江杭州,广西南宁,江西遂川、赣县,贵州石阡,湖南新宁,安徽黄山、贵池8个种源净籽率较低（60%～70%）,为皮油果用乌桕良种选育的种源材料。相关分析表明,与纬度密切相关的年均温度与≥10℃积温是影响乌桕种子性状的主要环境因子。 |

| Abstract: | The geographic variations among different provenances of Sapium sebiferum seeds were researched.The results showed that there were significant differences in the mass of 100 seed with testa wax(MSW) value among the provenances determined(F=4.52,P<0.01).The seed size of 7 provenances was large,and the MSW value was over 14 g,which belonged to large seed type.The seed size of 3 provenances was small,and the MSW value was below 10 g,which belonged to small seed type.Whereas the seed size of the provenances bel... |
