不同类型春小麦品种之间的特性有其共同规律和品种间的差异,掌握它们之间的异同能为育种和栽培提供一定理论依据,1979年我们对不同类型春小麦九个品种和品系进行了观察比较,主要是对叶片开始伸长期、持续时间、生长速度、生长量、定型期、叶面积,干物质积累及穗分化的发育过程,籽粒形成过程和粒重进行观察,以明确不同品种的生长发育特点,现总结如下:
The characteristics of different types of spring wheat varieties have their own common law and the differences among cultivars. To grasp the similarities and differences between them can provide some theoretical basis for breeding and cultivation. In 1979, we compared and observed nine varieties and strains of different types of spring wheat , Mainly to observe the development process of leaf elongation, duration, growth rate, growth rate, setting stage, leaf area, dry matter accumulation and ear differentiation, grain formation process and grain weight to clarify the growth and development of different varieties Features, are summarized as follows:
