| 摘 要： | 研究了不同生态型小麦在春季分期播种条件下的幼穗分化过程与温度效应的关系。结果表明,随播期后移,平均日均温升高,春型小麦幼穗分化历时缩短,但所需积温相对稳定;冬型小麦则幼穗分化历时延长,所需积温增加,且冬性越强,需积温越多。

| Abstract: | This paper deals with the relation between the young spike differentiation of dif-ferent ecotypes of wheat at different sowing date and the effect of temperature. The resultshow that the later the wheat is sowed and the higher the average temperature gets, theshorter the young spike differentiation of spring wheat lasts. The accumulated temperaturesthat it needed is relatively stable, the longer the process of the winter wheat lasts and thehigher accumulated temperatures are needed; The days and accumulated temperatures arehigher for winter wheat needed than spring wheat. |
