The seasonal maximum in photosynthetic CO2 exchange rate (CER) and the cessation of leaf expansion in soybeans (Glycine max (L.) Merr) accompany fruiting under normal agricultural conditions. To investigate whether these phenomena were obligatively tied together, we caused early flowering of long-season varieties by imposing artificial short-day treatments. Comparisons of CER and leaf area between vegetative (long-day treatment) and fruiting (short-day treatment) plants of long-season cultivar confirmed the relationship of these phenomena. The same comparisons made between a long-season and a short-season cultivar, both at the same daylength, also confirmed the relationship.
在正常农业条件下，大豆（Glycine max（L.）Merr）的光合作用 CO2 交换率（CER）的季节性最大值和叶片扩张的停止伴随着结实。为了研究这些现象是否必然联系在一起，我们通过施加人工短日处理使长季品种提前开花。长季品种营养生长期（长日处理）和结实期（短日处理）CER 和叶面积的比较证实了这些现象之间的关系。在相同的日照长度下，长季和短季品种之间的相同比较也证实了这种关系。
