先合作用的初生产物的本性尚未得到充分的研究,而在植物同化器官中通过酶的活动由初生产物构成的相对稳定的次生产物,则可借助于一般化学分析方法来加以测定。这些光合作用次生产物因高等生物体复杂而多方面的物质代谢而异,因而其本性在某种程度上是各个植物种和品种所特有的。在各个种的个 The nature of the pro-active primary product has not been well studied and relatively stable secondary products consisting of the primary product in the plant assimilation organ by enzymatic activity can be determined by means of general chemical analysis. These photosynthetic secondary products, which differ according to the complex and multi-dimensional metabolism of organisms in higher organisms, are to some extent unique to each plant species and variety. In all kinds of one
