叶形在树木叶片气体交换应对风胁迫中的作用

The effect of leaf shape on leaf gas exchange for trees

作为环境因子,风与树木的关系较其他因子复杂,树木对风胁迫的响应与适应是植物逆境生理生态学研究的热点和难点。本文综述了不同叶形树种叶片气体交换对风胁迫的响应差异,总结发现风对不同叶形树种叶片气体交换影响的研究结论差异较大,有的甚至截然相反,表明了不同叶形树种叶片气体交换对风胁迫响应的复杂性。同时分析了由叶形引起的微环境、边界层导度和理化特征对叶片气孔交换的影响。

Relationship between wind and tree is complexity. And the response and adaptation of tree to wind stress is the topic of ecophysiology. In this paper, we reviewed the differences responses of leaf gas exchange to wind stress for trees with different leaf shape, and found that there were huge differences, even polarity, for leaf exchange of trees with different leaf shape under wind stress. Meanwhile, we analyzed the efrect of leaf shape on leaf gas exchange through regulation micro envi- ronment, leaf boundary layer conductance and ecophysiology. Also, we proposed two topics on studying relationship between wind and tree.
