摘要
不同浓度的硒对植物生长有截然不同的作用,低浓度硒有益于植物生长,高浓度硒对大部分植物有毒害作用。随着人类对环境硒污染认识的加深,土壤硒污染及作物硒毒害等问题逐渐得到重视,这推动了对硒在植物中的吸收、积累及代谢调控的研究。总结了植物硒毒害方面的研究进展,包括土壤中硒的分布特征,不同植物硒毒害的阈值、表现特征以及毒害机制和抵抗毒害机制,并在此基础上提出未来硒毒害研究难点,为硒的合理利用提供参考。
Different selenium(Se) concentrations exhibit different effects on plant growth,low concentrations are beneficial to plant growth and development while high levels are toxic to most plants.With the deepening of people’s understanding of Se pollution in the environment,Se pollution in soil and Se poisonousness in crops have gradually attracted attention,which promotes the study of selenium absorption,accumulation and metabolic regulation in plants. This paper summarized the research progress of Se toxicity in plants,including the distribution characteristics of Se in soil,threshold values,manifestation characteristics of Se poisonousness,related toxicological basis,and toxic resistance in plants,and put forward the difficulties in the future research of Se toxicity,which would provide references for the rational utilization of Se.
