摘要
利用单色软X射线木材密度计 ,分别测定 2 2个杉木优良家系年轮宽度组成性状与年轮密度组成性状 ,通过遗传变异研究和遗传相关分析 ,了解杉木密度性状变异规律及与生长的关系 。
Cunninghamia lanceolata fine family annual ring width and density composition characteristics were determined respectively with the homogeneous soft X ray wood densimeter.Through the genetic variation research and interrelating analysis,the C.lanceolata density character variation law and relationship between it and growth are grasped,which provides the basis for early stage multiplecharacter selection.
