光温生态因子对冬小麦幼穗分化的影响研究

Effects of daylength and temperature on the spike differentiation of winter wheat

  • 摘要: 对不同播期3个不同生态类型冬小麦品种幼穗分化进程系统观察研究结果表明,单棱期和二棱期为冬小麦对光温最敏感时期,其他幼穗分化发育时期对光温的反应与品种生态类型有关;试验播期范围内光温生态因子对冬小麦幼穗发育进程的影响作用以温度为主;气候变暖下通过调整播种期可调控冬小麦的幼穗发育进程。

     

    Abstract: The spike differentiation processes of 3 winter wheat varieties under different sowing dates were studied.The results show that the excessive sensitive stages to daylength and temperature are single and double ridge stages of winter wheat,however the sensitivity of other stages to those is related to the ecological type of winter wheat.The major factor which affects the spike differentiation is the mean daily temperature in the experiment,therefore,the progress of spike differentiation of winter wheat could be regulated by controlling sowing date as climate becoming warm.
