关于玉米籽粒灌浆期源库限制的问题已做过一些研究。在源受限制的条件下,对籽粒灌浆有用的同化物不足以达到籽粒潜在重量。当库受限制时。表现为籽粒产量受到单位面积籽粒数目的限制,因此籽粒数目越多籽粒产量越
Some research has been done on the issue of source pool restriction during corn grain filling. Under limited source conditions, the available assimilates for grain filling are not sufficient to reach the potential weight of the grain. When the library is limited. The performance of the grain yield is limited by the number of grains per unit area, so the greater the number of grains, the greater the grain yield
