一、前言当前国内外对冬小麦穗分化研究资料较多,而对春小麦研究资料报导不多。特别是我省目前推广的高产和不同熟期品种的穗分化与主要性状研究的材料看到的较少。为了掌握春小麦幼穗分化发育过程,促进穗部各器官的发育,达到穗大粒多,提高产量的目的,根据不同品种主要性状特点,为拟订高产技术措施提供理论依据。特对我省不同熟期的春小麦穗分化与主要性状进行了初步的探讨。
I. Introduction At present, there is more research data on the spike differentiation of winter wheat at home and abroad, but few reports on the research data of spring wheat. In particular, the current promotion of the province’s high yield and maturity of different varieties of ear differentiation and the main traits of the material to see less. In order to grasp the process of spike differentiation and development of spring wheat, promote the development of various organs of panicle, achieve the purpose of increasing spike and grain size and yield, provide the theoretical basis for formulating high-yielding technical measures according to the characteristics of the main characters of different varieties. Special preliminary study was conducted on the spike differentiation and the main characters of spring wheat at different maturity stages in our province.
