| 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。

| Abstract: | This paper deals with the relationships between the young spike differenti-ation of different ecotypes of wheat at different sowing date in spring and leaf emergence.The result shows that leaf emergence on main stem at all spike differentiation stages varywith ecotype. The leaf emergence is higher of winter wheat than those of spring wheat; Allleaf emergence on main stem at same spike differentiation stage experiences of different e-cotypes of wheat are not equal. |

| Keywords: | wheat ecotype extremely cold and semi-arid region young spike differentiation leaf emergence |
