【摘要】 为了研究大穗型和多穗型冬小麦分蘖成穗调控因子及其调节机理,实现产量提升,本文归纳了遗传因素、群体环境因素、内源激素等方面对不同类型品种分蘖成穗特性影响的研究进展。认为,以后研究应侧重于多种分蘖调控因子的影响机制及因子间的关系,通过研究分蘖过程中内源激素含量、激素间平衡及基因表达、调控与小麦分蘖发生关系的研究,以期为小麦高产栽培研究提供理论依据和技术支持。更多还原

【Abstract】 To research the regulation factors and regulating mechanism for tillering and earring of large-spike and multi-spike cultivars of winter wheat,and achieve yield improvement,this article summarized the research progress of the influence of genetic factors,group environment factors and endogenous hormones on tillering and earring of different spike cultivars of winter wheat,and pointed out that the future research should focus on the relationship between various factors and influencing mechanism of regulation factors of different tillers.According to studying the relationship among content of hormone,hormones balance,gene expression and regulation,and wheat tillering,this article will provide theoretical basis and technical support for high-yield cultivation of winter wheat.更多还原
