| 摘 要： | 对引进树种奥地利黑松1年生容器苗根系与地上部分生长关系进行了调查研究。结果表明,奥地利黑松苗高和地径生长量与根系生物量极显著相关。苗高生长量与侧根鲜重关系最密切,地径生长量受根系鲜重影响最大。应用逐步回归法建立了苗高、地径生长量与根系生长关系的最优回归方程。

| Abstract: | This paper deals with relationship between root system and the above-ground growth of one-year-old seedlings of Pinus nigra The result shows that the stem growth is highly relevant to root biomass,and that the height growth has a close relationship with fresh wight of lateral roots,and diameter increment of stem is affected by fresh wight of root system significantly.The best-fit regression equation was set up for seedlings height,stem diameter and root growth of Pinus nigra through the method of stepwise regression. |
