| 摘 要： | 本文采用27个马尾松天然林优树自由授粉家系苗期和幼龄期的材料,分析了高径和冠幅等生长性状的遗传变异。结果表明:在苗期和幼龄期,树高和地径的遗传变异性很大,呈中度至强度遗传,遗传力有随年龄增大而减少,并渐为稳定的趋势。性状间呈高度遗传相关。

| Abstract: | 27 open-pollinated families from natural stands of masson pine were used as test material. The inheritance and variation of their juvenile growth traits, i. e. height, base diameter and crown size were analysed. The results showed that genetic variation of tree height and diameter at base was significant. It appeared that there was a moderate or a strong degree of additive genetic control for both traits, whose heritabilities tended to decrease as its age was increasing. The strong genetic correlation between growth traits was found. |
