蔬菜富硒规律及生理生化作用研究进展

Research Progress on Selenium-rich Law of Vegetables and Physiological and Biochemical Function

在总结蔬菜富硒基本规律的基础上,从硒对蔬菜种子萌发及幼苗生长、生长发育及产量品质形成、抗性及与其他重金属互作的生理生化的影响等方面进行综述。在适宜硒浓度生长环境下,硒对蔬菜种子萌发及植株生长促进、产量及品质优化、抗性提升、重金属毒害缓解等方面的影响明显;而超量的硒则表现出毒害作用。展望我国富硒蔬菜产业发展及未来方向,提出应优选富硒蔬菜品种、规范蔬菜富硒安全栽培模式,为促进富硒蔬菜产业发展提供参考依据。

The effect of selenium on seed germination and seedling growth,plant growth and development,yield and quality formation,resistance to vegetables and the physiological and biochemical effect of interacting with other heavy metals were summarized on the basis of summarizing the basic law of selenium enrichment in vegetables.It was emphasized that under the growth environment with suitable selenium concentration,selenium had obvious effect on seed germination,plant growth promotion,yield and quality optimization,resistance improvement and toxicity alleviation of heavy metals,while excess selenium showed poisoning effect.Finally,the development and future direction of selenium-rich vegetable industry in China were briefly analyzed.It was suggested that selenium-rich vegetable varieties should be optimized and the safe cultivation mode of selenium-rich vegetables should be standardized to provide reference for promoting the development of selenium-rich vegetable industry.
