| Abstract: | The total grain number of a female corn ear is decided 18 days after its silking while that of its underdeveloped grain is fixei 8~28 days after silking, In one word, the effective corn grain is developed into within 3-4days after silking. In the course of high-yielded cultivation, such factors as measures and weather conditions have remarkable effects on both late underdeveloped grain and those on the lower part of a female corn ear. |
