| 摘 要： | 对国外荚蒾属9个树种的形态特征、生长适应性与物候期进行了研究,通过测量、数据整理和统计分析,用Logistic方程对9个树种的年生长高度和年生长冠径的规律进行了拟合。Logistic方程能合理地表达9个国外荚蒾属观赏树种的苗高年和冠幅年生长动态,相关系数均为0.99以上。9个树种的年生长期可分为生长初期、生长盛期、生长后期。

| Abstract: | We investigated the form characteristics, growth adaptability and seasonal appearance in 9 species of Viburnum.On the basis of measure,data and statistic analysis,annual growth regulations were concluded by Logistic equations,by which the height and coronal growth dynamics of Viburnum could be expressed,and its correlation coefficient attained 0.99 or above.According to the Logistic equations,it was found that annual growth period included initial stage,flourishing stage and anaphase stage.The results above-mentioned provided important evidence for introduction and domestication of exotic Viburnum plants. |
