摘要
株高是玉米理想株型的重要指标,与产量密切相关,影响着植物光合利用率、抗倒伏性、收获指数等。植物激素通过影响细胞的分裂和伸长来改变玉米的节间长度和数目,从而调节玉米高度达到矮化的效果。文章综述了近年来控制玉米株高的QTL/基因定位和克隆的研究进展以及激素(GA3、IAA、BR)调控下矮化突变体的形成,以期为玉米育种生产和应用提供参考。
Plant height is an important indicator of the ideal plant type of maize and closely related to yield.It affects plant photosynthetic utilization,lodging resistance,harvest index,etc.By altering cell division and elongation,phytohormones change the length and quantity of maize internodes,modifying maize plant height to achieve the effect of dwarfing crops.This paper reviewed the research progress in recent years on the mapping and cloning of QTL/genes that control maize plant height and the formation of dwarf mutants under the regulation of hormones(GA3,IAA,BR),in order to provide references for the production and application of maize breeding.
