摘要: 分蘖成穗是小麦高产栽培中决定群体数量和质量的关键因素。为了研究不同穗型冬小麦分蘖成穗特性及其调节机理,进而提高小麦产量,研究归纳了遗传因素、群体环境因素、内源激素等方面对不同穗型品种分蘖成穗特性影响的研究进展。指出以后研究应侧重于各种因素影响分蘖发生的机制以及因素间的关系,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。

Abstract: Tillering, which affects the number of panicle and grain production, is a key factor for the quality and quantity of population in high-yield cultivation. In order to research the characteristics and mechanism of tillering and earring of different spike cultivars and then increase the grain yield of wheat, this article summarized the researching progresses with reference to genetic factors, group of environmental factors, endogenous hormones and other aspects, and pointed out that the future research should focus on the relationship between various factors and mechanism which influences tillering. By studying the relationship among content of hormone, hormones balance, gene expression and regulation, and wheat tillering, this article provided a theoretical basis for research on wheat high- yield cultivation.
