叶绿素是绿色植物进行光合作用的主要色素。不同树种其叶绿素含量不同,不同地理种源的同一树种,叶绿素也有明显的差异。在热带珍贵树种母生类型之间,叶片和树皮栓内层的绿色程度存在着明显的差异,也是母生类型划分的重要依据之一。为了寻找叶绿素含量与母生类型之间的数量关系,我们于1977年10月至1978年2月对母生的两种典型(厚皮类型和薄皮类型)的叶绿素含量进行了比较分析,以期为类型划分提供进一步的依据。
Chlorophyll is the main pigment for photosynthesis of green plants. Different species of chlorophyll content is different, the same species of different geographical provenance, chlorophyll also have significant differences. There is a clear difference in the green degree between the inner layers of the leaves and the bark of the tree among the mother species of tropical precious tree species, which is also one of the important grounds for the classification of the mother type. In order to find the quantitative relationship between chlorophyll content and mother type, we compared the chlorophyll contents of two typical (thick-skinned and thin-skinned) mother species from October 1977 to February 1978 with a view to Type division provide further basis.
