| 摘 要： | 本文对８个产地大青杨天然群体，１个产地大青杨群体内不同个体，２个产地香杨群体幼苗基本材性进行了研究，测定了纤维长度、纤维宽度和基本密度。结果表明：８个大青杨群体间，１个大青杨群体内１０个个体幼苗３个材性主要指标，纤维长度、宽度和基本密度差异显著；纤维长度和基本密度的广义遗传力，大青杨天然群体间为０．２２５和０．２１７，群体内为０．４７５和０．３４５。本研究同时对大青杨群体内、群体内的个体进行了优选

| Abstract: | Among 8 juvenile populations and 10 individuals within 1 juvenile population were collected from Heilongjiang and Jilin Provinces.In this paper,the fiber length,fiber width and basic density were studied,the analysis of variance indicated that there were significant differences.The broad sense heritabilities were fiber length (0.225) and basic density (0.217) among 8 populations and fiber length(0.475) and basic density (0.345) within 1 population. 3 fine populations and 4 fine individuals of a population have been selected.A significant positive at 0.05 level were exhibited between wood density and latitude.The relation between fiber length and latitude was lower. |
