烟草早花机理研究进展

Review on Research of Tobacco Premature Flowering Mechanism

早花严重影响着烟草的质量与产量,随着对植物开花机理研究的不断深入,对烟草早花的研究也已从对温度、光照、水分和养分等生理方面的研究发展到了分子水平研究,然而烟草早花的成因及其影响因素至今仍未有明确的定论。从影响烟草成花的生理与分子机理及外界环境条件等方面进行分析和综述,以期为传统的研究方法与分子技术相结合提供参考依据,为烟草早花机理的研究提供参考。

Early flowering has deeply effect on the quality and yield of tobacco. With the developing of plant flowering research, the research of tobacco premature flowering was not just only on light, temperature, water, and nutrient, but also on molecular research. Causes of tobacco premature flowering are stiU not clear. This paper summarized and analyzed the influence of tobacco-flowering-time from many aspects, including physiological mechanism, molecular mechanism and external environment condition. Combining traditional research with the molecular research, we can expound all the problems comprehensive and find the way to solve them. It has great significance of the research of tobacco premature flowering.
