玉米雄穗分化发育研究进展

Research Progress on Differentiation and Development of Tassel in Maize

玉米雄穗分化发育状况及其性状特征与产量关系密切。在总结和了解国内外相关研究成果的基础上,对玉米雄穗分化发育与外部器官同伸关系、影响玉米雄穗分化发育的因素、雄穗分化发育过程中生理活性物质的动态变化进行了简要综述,阐述了利用玉米叶龄指数预报雄穗分化发育进程的方法,为指标化管理玉米生产栽培提供一定的理论依据,对雄穗分化发育研究方向进行了展望,并提出需进一步解决的问题。

The differentiation and development of tassel and its characters related closely to the yield of maize. Based on the relevant home and abroad research, the synchronous relation between differentiation and development of tassel of maize and external organisms, the factors affecting the differentiation and development of tassel of maize, the dynamic changes of physiologically active substances in process of differentiation and development of tassel of maize had been briefly reviewed, the method of applying the leaf number index of maize to forecast the process of differentiation and development of tassel had been explained, which provided some theoretical basis for indexing management of production of maize. At the same time, the research on the differentiation and development of tassel was prospected, and the problems to be solved were put forward.
