| 摘 要： | 通过育苗对比试验, 对奥地利黑松Pinus nigra var .austriaca 和油松P .tabulaeformis 1年生苗生长量和生物量进行了调查测定。结果表明, 奥地利黑松1 年生苗地径生长量显著大于油松, 且主、侧根发达, 而油松高生长量显著大于奥地利黑松。多元线性回归分析表明,2 个树种的高生长量、径生长量与侧根鲜质量、根系鲜质量呈极显著相关, 并且高生长量与侧根鲜质量、径生长与根系鲜质量关系最为密切。表2 参5

| Abstract: | The comparative studies were conducted by methods of field tests andmuti-line regression analysis .The results showed that the diameter increments of one-year-old seedling of Pinus nigra var. austriaca was bigger than that of Pinus tabuleaformis , and its tap and lateral roots were more developed , while the height growth ofPinus tabuleaformis was bigger .Multi-line regression analysis showed that the correlation between the seedlings' height and fresh weight of lateral roots , and between diameter growth and fresh weight of roots were all very significant .
