烟草中活性氧的研究进展

烟草在衰老过程中和逆境条件下会产生大量活性氧,活性氧会导致细胞的氧化甚至死亡,然而适当浓度的活性氧会增加植物的抗虫抗病性。为了更好地了解烟草中活性氧的来源和作用,本文归纳总结了烟草中活性氧的产生原因、功能和测定方法等,并在文章的最后做出总结和展望。

Research progress on reactive oxygen species in tobacco

Tobacco will produce a lot of reactive oxygen species in the process of aging and stress conditions, which will lead to cell oxidation and even death. However, the appropriate concentration of reactive oxygen species will increase the resistance of plants to insects and diseases. In order to better understand the source and role of active oxygen in tobacco, this article summarizes the causes, functions and measurement methods of active oxygen in tobacco, and makes a summary and prospect at the end of the article.
