摘要
对美洲黑杨×小叶杨新无系木材性状遗传相关分析结果表明,年轮宽度与早材宽度、晚格宽度遗传相关比较密切,与晚材率之间相关很弱;而年轮密度与材密度,晚材密度,最小密度及最大密度霜关密切,晚材密度比及木材密度梯度相关很弱,年轮密度与年轮宽度之间呈负弱相关。
In this paper the genetic correlation analysis on wood properties of nwe 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.
