摘要
利用龙麦26和垦大4号两个小麦品种,调查了不同粒位结实率和粒重的情况.结果表明,小穗中结实率最高的小花为每小穗的最基部小花,结实率最高的小穗在每穗的中下部;小穗中最重的粒位为每小穗基部的第1粒位或第2粒位。粒重最高的小穗在每穗的中下部。
In order to research the setting percentage and the grain weight of spring wheat, two varieties Longmai 26 and Kenda 4 were used. The results showed that the florets with highest setting percentage were located in lower part of spikelet, the spikelets with highest setting percentage were located in middle-lower part of ear, the highest weight grains lay on first or second place of spikelet, but the highest weight spikelets lay on lower position of ear.
