【摘要】 在功能性农业快速发展的背景下,富硒园艺产品因其独特的营养价值和保健功能备受重视。硒作为人体必需的微量元素,具有抗氧化、免疫调节和抗癌等生理功能,但全球约40%的土壤存在硒缺乏问题。围绕“园艺作物—硒生物强化—生理效应”的相互作用关系,系统分析了:1)硒在园艺作物中的富集机制与代谢途径;2)硒生物强化对作物生理特性及产品品质的影响;3)当前富硒产业发展的关键技术瓶颈。通过探讨硒强化与园艺产品品质形成的关联机制,提出了富硒产业标准化发展的策略建议,为提升园艺产品附加值和产业竞争力提供理论支撑。更多还原

【Abstract】 In the context of the rapid development of functional agriculture,selenium-enriched horticultural products are highly valued for their unique nutritional value and health care functions.Selenium,as an essential trace element,has physiological functions such as antioxidant,immunomodulatory and anticancer,but about 40% of the soil in the world is selenium-deficient.This paper focuses on the interaction relationship of "horticultural crops-selenium biofortification—physiological effects ",and systematically analyzes:1)mechanism and metabolic pathway of selenium enrichment in horticultural crops.2) the effects of selenium biofortification on the physiological characteristics of the crops and the quality of the products.3) the key technological bottlenecks for the development of selenium—enriched industry at the present time.By exploring the correlation mechanism between selenium fortification and the formation of horticultural product quality,strategic suggestions for the standardized development of selenium—enriched industry are put forward to provide theoretical support for the enhancement of the added value of horticultural products and the competitiveness of the industry.更多还原
