摘　　要：玉米雌雄穗分化发育具有特殊的规律,而且受到多种因素的影响,穗发育的优劣又决定玉米产量的高低。分析了多种因素对玉米雌雄穗分化发育的影响,指出干旱等逆境对玉米雌雄穗发育及产量有重大作用。简要阐述了开花间隔、种植密度等对产量的影响。The differentiation and growth of the male and female maize ears have special ways and were affected by many factors,and even the growth condition of maize ear also effect the production.In the paper,we summarized the differentiation and growth of the male and female maize ears,analyzed the effect of variety factors to its differentiation and growth and pointed out that drought stress had significant effect to the differentiation and yield.The relationship between anthesis-silking interval and planting density with yield was also discussed.
