【摘要】 陈山红心杉具有地方特色的杉木优良种源。以陈山红心杉伐蔸直径与红心直径为研究对象，研究表明陈山红心杉中央直径长、红心直径长及红心比例呈显著正相关。陈山红心杉生长性状与心材颜色呈弱相关关系，陈山红心杉个体间红心比例也存在显著的差异，因此，陈山红心杉心材材色具有很大的选择和改良潜力，具有选择材色优良无性系的可能。更多还原

【Abstract】 Chenshan red fir has local characteristics of Chinese fir provenances,this study to Chenshan red fir stump diameter and diameter as the object of study, the results showed that the central diameter length, the red heart diameter length and the red heart proportion were positively correlated. There was a weak correlation between the heartwood color and the growth traits of C. chenshanensis,and there was also a significant difference in the ratio of heartwood color among individuals of C. chenshanensis, so the heartwood color of C. chenshanensis has a great potential for selection and improvement, it was possible to select clones with good material color.更多还原
