摘要/Abstract

摘要： 对窄冠福建柏和福建柏的冠型结构、枝系特征和叶片形态特征进行分析,结果表明,在年龄和环境条件基本一致的情况下,二者对环境条件变化的适应策略不同:1)窄冠福建柏的冠长、冠幅和树冠率均小于福建柏,而树高和胸径则显著大于福建柏。2)福建柏各生长阶段的总体分枝率、逐步分枝率、一级枝长度、枝径比及枝倾角均大于窄冠福建柏。3)二者总体分枝率在幼苗、幼树阶段差异不显著,在成树阶段达到显著水平;逐步分枝率除幼苗和成树阶段SBR_1:2差异显著,其它生长阶段的逐步分枝率差异都不显著;一级枝长度、枝径比及枝倾角差异均达到极显著水平。4)从叶片特征看,二者叶片长度在幼苗阶段差异显著,叶片宽度和长宽比在幼树、成树阶段差异显著,叶面积在各生长阶段差异均达到显著水平。

Abstract: The crown structure,branching characteristics and leaf characteristics of Fokienia hodginsii and its variant types at different growth stages were studied in this paper.The results showed that their adaptation strategy to the environmental conditions was different.The crown length,crown width and crown ratio of F.hodginsii variant types were all smaller than F.hodginsii;while the tree height and diameter at breast height were all significantly larger than F.hodginsii.The overall bifurcation ratio,stepwise bifurcation ratio,length of the first order branch,ratio of branch diameter and leaf angle to horizon of F.hodginsii were all larger than its variant types.As for the F.hodginsii and its variant types,the difference of overall bifurcation ratio was non-significant at the seedling stage and sapling stage,and significant at thetree spanning stage;the difference of stepwise bifurcation ratio SBR_2:1 was significant at the seedling stage and tree spanning stage,and the stepwise bifurcation ratio of other growth stage were non-significant;the difference of length of the first order branch,ratio of branch diameter and leaf angle to horizon were all significant at the seedling stage,sapling stage and tree spanning stage.The leaf length of the F.hodginsii and its variant types was significantly different at the seedling stage;the leaf width and leaf length to width ratio of the F.hodginsii and its variant types were significantly different at the sapling stage and spanning tree stage;and the leaf area was significantly different at the seedling stage,sapling stage and tree spanning stage.
