摘要
选取刚竹属的绿皮黄筋竹、乌芽竹、高节竹等3个竹种为研究对象,测定各竹种叶片与叶鞘的质量,用幂指数函数模型进行拟合,分析叶片与叶鞘的异速生长关系。结果显示:绿皮黄筋竹、乌芽竹、高节竹等3个竹种叶片和叶鞘的生长指数分别为0.651、0.318、0.596,其生长关系呈现出不同的异速生长关系。
The leaf blade mass and leaf sheath mass of three bamboo species in Phyllostachys, i.e. Ph. sulphurea,Ph, atrovaginata and Ph. prominens,were measured, and their allometric growth relationships between leaf blade and leaf sheath were studied using the power exponential function model. The results showed that their growth index were 0.651, 0.318 and 0. 596 respectively, indicating varying degrees of allometric growth.
