国内外学者对冬春性小麦在遗传、生理上的差异,对春化和光周期的反应,生长发育规律及生育阶段的划分进行了大量的研究。本研究将来自全国各地的冬性、半冬性、春性小麦品种进行分期播种,对生育期、主茎叶片数、株高、穗长、实粒穗数、幼穗分化进程等进行了初步研究,同时就冬春性划分标准及生育阶段划分和光温效应等问题进行了初步探讨。 Domestic and foreign scholars conducted a lot of research on the genetic and physiological differences between winter and spring wheat, the reaction to vernalization and photoperiod, the growth and development and the division of the fertility stage. In this study, winter, semi-winter, spring wheat varieties from all over the country were sown in stages, and the growth stages, number of main stem leaves, plant height, spike length, number of spikelets per panicle, Preliminary study, at the same time on the spring and winter division of the standard and the division of stages of birth and light temperature effects and other issues were discussed.
