不同温度处理条件下植物种子萌发的研究进展

Research Progress of Different Temperatures Treated Plants Seed Germination

种子萌发是植物生长发育的开始,具有非常重要的生物学意义。研究表明不同的温度处理可以有效提高植物种子的萌发效率,尤其是低温处理条件下效果明显且应用广泛。本文对不同温度处理促进种子萌发的研究方法和低温处理条件下种子内源激素的变化等进行了综述,并对今后的研究重点和方向进行了展望。

For seed plants, the seed germination is the beginning of plant growth and development. There are extensive methodological researches on improvement of seed germination with different temperature treatments, among which low temperature induction can effectively increase the frequency of seed germination. This paper summarized the research progress on methods of seed germination and molecular events such as the change of endogenous phytohormones. Finally the research direction for the low temperature induced plants seed germination is prospected.
