摘要：３２个杉木无性系间，木材密度和抗弯弹性模量、抗弯强度、顺纹抗压强度均有较大差异；无性系内株间亦存在一定差异。木材密度与抗弯弹性模量、抗弯强度、顺纹抗压强度间的相关极显著，相关系数分别为０．３９５７、０．８３６８和０．９０２０；木材密度与生长速度呈负的遗传相关。
Wood density and mechanical properties of 32 Chinese fir(Cunninghamialanceolata(Lamb.Hook.)were determined and analysed.The results showed that therewere remarkable differences in wood density,MOE,MOR,and crushing strength amongthe clones,and there were also considerable intraclonal differences as well. Significant posi-tive correlations at 0.01 level were exhibited between wood densitv and MOE,MOR,crush-ing strength with the correlation coefficients 0.395 7,0.836 8,and 0.902 0 respectively.Wood density was negatively correlated to the diameter at breast height.
