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进程与叶片出生的关系。结果表明:小麦叶龄与幼穗分化时期的对应关系因生态型而异,冬性品种幼穗分化各时期对应的叶龄均高于春性品种,不同生态型小麦幼穗分化同一时期内经历的叶片数目不尽相同。
The relationship between spike differentiation and leaf emergence of different ecotypes of wheat under sowing conditions in spring was studied. The results showed that the corresponding relationship between wheat leaf age and panicle differentiation was ecotype. The corresponding leaf ages of winter wheat varieties were higher than those of spring varieties at different stages of panicle differentiation. Earner differentiation of different ecological wheat during the same period The number of leaves varies.
