东北“三大硬阔”叶片和叶轴质量分配比较
|
摘要
以3个树种健康复叶为试材,研究了叶内光合构件和支撑构件的生物量投资的种内种间变化规律。结果表明:水曲柳、胡桃楸和黄檗叶轴质量占复叶质量的比例分别为0.18、0.26和0.17,胡桃楸显著大于其它2个树种。跨物种尺度上,复叶大的树种需要更多的叶内支撑结构投资。但物种水平上,水曲柳叶片投资随叶增大而增大,胡桃楸则降低,黄檗基本稳定,表现出与跨物种水平上的叶片投资随叶增大而降低的普遍规律不同。今后需要加深物种水平上叶内生物量分配的异速生长的了解。
We used the healthy compound leaves of Fraxinus mandshurica( FM),Juglans mandshurica( JM) and Phellodendron amurense( PA),we investigated the variations in biomass allocation between photosynthetic components and supporting components within leafs at the intra-and inter-species scales. The mean ratios of rachis to the compound leaf for FM,JM and PA were 0.18,0.26 and 0.17,respectively,with the value for the JM significantly higher than those of the other two species. Across species,the species with large compound need higher within-leaf investment to the supporting component. For particular species,however,with the biomass of compound leaf increasing,the lamina increased for the FM,but that decreased for the JM,and that for the PA was relative stable. There was a different pattern within species with the decreasing investment to lamina for larger compound leaf across species. It is necessary to improve the understanding of the allometry of biomass allocation within compound leaves at a species scale.
