| 摘 要： | 通过育苗对比试验,对奥地利黑松Pinus nigra vat．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 and muti-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 of Pinus 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.[Ch,2 tab.5 ref.] |
