摘要
为了解春小麦穗分化的不同阶段对小穗数的影响,以小穗数有差异的5个小麦品种为材料,对其穗分化各个阶段的天数与总小穗数进行通径分析,结果表明:尽量加快伸长期、单棱期的分化速率,缩短这2个分化时期的时间、延长二棱期分化的天数是提高春麦总小穗数的途径。
The paths analysis between days in each spike differentiation stage and spikelets of spring wheat were studied with 5 wheat cultivars different in spikelets,it was in order to reveal the impact of spike differentiation stage on wheat spikelets.The results showed that :accelerating the development rate of elongation and single edge stages of growth point and shorting the development days of these two stages were ways of increasing the spikelets of spring wheat.
