Conversely, as competition for light decreases, there should be an increasing premium on branching that is achieved through weaker apicaldominance to maximize light capture.
相反地，当光竞争减弱时，植物的顶端优势较弱，加强分枝结构以增大对光的截获。

It was also observed that the "inter-grain apicaldominance" in hybrid rice was stronger than its restorer, which might be one of the main reasons for low seed setting in hybrid rice combination.
