摘要：

对美洲黑杨×小叶杨新无性系木材性状遗传相关分析结果表明,年轮宽度与早材宽度、晚材宽度遗传相关比较密切;与晚材率之间相关很弱;而年轮密度与早材密度、晚材密度、最小密度及最大密度之间遗传相关密切(r_y=0.84-0.95),与早晚材密度比及木材密度相关很弱;年轮密度与年轮宽度之间呈负弱相关。

关键词: 美洲黑杨×小叶杨, 年轮密度组成, 年轮宽度组成, 遗传相关分析

Abstract:

In this paper the genetic correlation analysis on wood properties of new clones of Populus deltoides×P.Simonii was studied.The results showed that ring width was closely related to both earlywood width and latewood width genetically, but hardly related to latewood percentage.Ring density was closdly interrelated to the other wood traits genetically(r= 0.84—0.95), including earlywood density, latewood density, the minimum wood density and the maximum wood density, but weakly related tO both early—late wood density rate and the gradient of wood density.Moreover, the genetic relationship between ring width and ring density was negatie and very weak.
