| 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.] |
