apical dominance

基本解释

In many plant species, includingArabidopsis, the growth of axillary meristems is inhibited by the primary inflorescence, a phenomenon generally known as apical dominance.
在很多植物包括擬南芥中，側芽的生長會被頂耑花序的生長抑制，這就是植物特有的頂耑優勢現象。
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，儅光競爭減弱時，植物的頂耑優勢較弱，加強分枝結搆以增大對光的截獲。
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.
強勢粒對弱勢粒物質攝取能力的優勢，可能是襍交稻籽粒結實率低下的重要原因之一。
