云南松同化器官数量垂直分布的规律

植物的同化器官一般是指制造和积累有机物质并用于满足植物生长发育需要的叶片(叶束)。它是植物的重要组成成分。同化器官吸收光能,在叶绿体和酶的作用下将二氧化碳和水合成为碳水化合物。它的数量的多少决定了植株制造有机物质的能力,直接关系到森林生态系统第一性生产力的高低。因此,研究植物群体和单株同化器官数量垂直分布的规律及其与

THE LAW OF ASSIMILATION ORGANS QUANTITY VERTICAL DISTRIBUTION OF PINUS YUNNANENSIS FRANCH

This paper deals with the law of assimilation organs quantity vertical distribution of Pimis yunnanensis Franch, and the influence caused by different developing ages of plant, the stand density, the slope and the elevation to the law. Mathematical equation was used to describe it. This law will help to understand the effect of the assimilation quantity vertical distribution on population productive ability and the reason for the change of plant diameter growth and the model for the change of vertical distr...
