因缺少性状的比较,我们对亚热带山地森林木质藤本和树木的与生态适应策略有关的功能性状变异格局仍知之甚少。本文通过研究中国西南亚热带山地森林中不同叶片习性的33种植物(7种落叶和4种常绿木质藤本、10种落叶和12种常绿树木)的13个性状的分化来填补此空白。研究结果表明,木质藤本的枝条木质部导管直径、理论导水率、比叶面积、叶片氮和磷含量显著高于树木,但其叶片干物质含量和氮磷比显著低于同域分布的树木,表明木质藤本采取获取的生态策略,具有更高效的枝条导水系统和生产力更强的叶片。与树木相比,木质藤本的导管直径变异更大,同时具有一些大导管和很多小导管,说明木质藤本具有较大的导管二型性。生长型解释了性状总变异的48.7%,叶片习性仅解释了3.8%的总变异,生长型和叶片习性之间没有显著的交互作用。此外,枝叶性状仅在树木中存在显著相关,木质藤本中不存在,表明亚热带木质藤本枝条的水力功能与叶片的性状是解耦的。上述结果表明,亚热带山地木质藤本和树木的枝条和叶片功能性状存在显著差异。加强对亚热带山地生态系统中木质藤本和树木生态策略差异机制的认识还需要深入研究。

为了确定幼儿心功能测评方法,选择了3种不同的运动负荷量,即“30s30次蹲起”、“30s20次蹲起”、“45s30次蹲起”,对1412名3～6岁幼儿进行实验、对比发现,处于发育期的幼儿不宜进行大强度负荷的运动实验,静态的心率、血压测评也难以对心血管功能作出有效的评定。因此,最终确定以“45s30次蹲起”的定量负荷测评作为该年龄阶段心功能评价科学、有效、简便易行的方法。
