小麦穗上开花顺序和开花概率分布以穗轴中部为中心呈离心规律分布,结实概率分布与开花概率分布密切相关,趋势一致。这种概率的大小和分布反映了增粒潜力的大小和难易程度,也是小穗和小花结实性的优势与劣势的划分标准。增加粒数的调控序列为:促进幼穗的小穗分化,防止小花退化,力争多开花,提高开花结实率。促进多花多粒是实现高产的关键性技术途径。
The flowering order and flowering probability distribution of wheat spikes were centered in the middle of the cob on a centrifuge pattern, and the probability distribution was closely related to the probability distribution of flowering and the trend was the same. The size and distribution of such probabilities reflect the size and ease of potential for granulation and are criteria for dividing the strengths and weaknesses of the robustness of spikelets and florets. Increasing the number of grain control sequences are: to promote young spikelet differentiation, to prevent floret degradation, and strive to more flowering, and improve the rate of flowering and fruiting. To promote more flowers and more grain is the key technology to achieve high yield.
