关于小麦幼穗分化发育的研究,国内外虽有资料报道,但广东地处热带和亚热带气候,属华南早熟冬麦区,品种属比较典型早熟春性类型,其生态条件及生产上采用的品种与其它麦区不同。究竟广东的小麦幼穗分化发育有何特点?不同热期品种之间穗分化进程有何不同?穗分化进程与植株外部形态的生长有何联系?在生产上采用那些形态作为管理的指标?以前尚无系统研究。对此,本试检设置不同熟期品种和不同播种期,对广东小麦幼穗分化发育进程及其与外部形态的关系进行研究。
Although there are some reports at home and abroad, Guangdong is located in the tropical and subtropical climate and belongs to the early mature winter wheat region of South China. The varieties are typical early spring spring types, and their ecological conditions and varieties used in production Different from other wheat fields. What are the characteristics of differentiation and development of wheat spikelets in Guangdong? What is the difference in the process of spike differentiation between different hot varieties? What is the relationship between the process of spike differentiation and the growth of plant external morphology? No systematic research yet. In this study, the test set different maturity varieties and different sowing dates, the differentiation of wheat spike development process and its relationship with the external morphology of the study.
