对梓树进行不同密度的移栽，研究其叶片可塑生长的密度依赖性以及主要叶片性状因子之间的关系。结果表明，随种植密度增加，叶面积、叶干物质含量、生物量呈减少趋势；比叶面积呈先增大后减小趋势。比叶面积与叶片厚度、叶干物质含量之间均呈极显著的负相关，与相对叶绿素含量之间相关性不显著。叶片厚度和叶干物质含量与其它叶性因子的关系较为复杂，在不同种植密度下两者既表现出正相关关系，又表现出负相关关系。

Catalpa ovata G. Don was transplanted in different planting desity, and the density dependence of leave pliant growth and the relationship between the traits factor of leaves were studied. The results showed that the differences of the leaf area, biomass, specific leaf area, leaf dry matter content were significant with the density increasing . There was a negative correlation between the specific leaf area and leaf thickness, leaf dry matter content, and there was no significant correlation between specific leaf area and chlorophyll content . The analysis on traits factor of leaves showed that the correlation of Leaf thickness and leaf dry matter content and other leaf traits were more complex relationship, and a positive correlation between both, but also exhibits a negative correlation under the different planting density.
