大葱花序中小花数目较多，不同气候条件雄蕊散粉数量和花粉生活能力以及雌蕊受精能力有所差异。大葱雄性不育系人工授粉结实率不高，影响其选育进程和在生产上的应用。因此，探索大葱雄性不育系在不同气候条件下人工授粉结实率具有一定意义。1材料与方法试验以辽宁省风沙地改良
The number of small flowers in the verdant is more, the number of stamen loose powder and pollen viability in different climatic conditions are different, and the pistil fertilization ability is different. Onion male sterile line of artificial pollination rate is not high, affecting the breeding process and its application in production. Therefore, to explore the green onion male sterile lines artificial pollination rate in different climates is of some significance. 1 Materials and Methods The experiment was carried out to improve the sand area in Liaoning Province
