1·Conversely, as competition for light decreases, there should be an increasing premium on branching that is achieved through weaker apical dominance 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。

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

强势粒对弱势粒物质摄取能力的优势，可能是杂交稻籽粒结实率低下的重要原因之一。
