大豆开花前的光合产物很少被转运到发育中的籽粒中去,输送到籽粒中的光合产物有90％以上是在籽粒生长发育过程中形成的。因此,多数报道往往集巾于研究籽粒灌浆期叶冠同化物供应和产量表现的相互关系,仅有少数研究涉及源库平衡和产量组分的建成。大豆叶冠结构和功能与产量库建成的相互关系还未弄清,在人工调节源库比的场合,摘除部分小叶,产量库容并无明显变 Soybean pre-flowering photosynthate is rarely transported to developing kernels, and more than 90% of the photosynthetic products transported to kernels are formed during grain growth and development. Therefore, most reports often focus on the correlation between leaf-crown supply and yield performance during grain filling. Only a few studies have involved the balance of source and sinks and the production of yield components. Soybean leaf crown structure and function of the relationship between the production base has not yet been clarified, in the manual adjustment of the source library than the occasion, removal of some leaflets, yield and storage capacity did not change significantly
