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。
Tilting to spike is the key factor to determine population quantity and quality in high-yielding wheat. In order to study the characteristics of tillering panicles and their regulation mechanism in different panicle types of winter wheat and further improve the yield of wheat, the research progress on the effects of genetic factors, population environmental factors and endogenous hormones on tillering panicle characteristics of different panicle types was studied. It is pointed out that the future research should focus on the mechanism of various factors affecting tillering and the relationship between the factors. By studying the relationship between endogenous hormones and hormone balance and gene expression during tillering, Cultivation studies provide a theoretical basis.
