摘要
硝酸盐是一类极易在蔬菜特别是叶菜类蔬菜中高量累积的物质,过量摄入硝酸盐对人体健康存在极大的潜在危害。光照是影响植物硝酸盐累积最重要的环境因子之一,笔者分别从光强、光质、光照时间3个方面综述了光对蔬菜硝酸盐累积的影响,阐述了传统的昼夜交替光照模式下蔬菜硝酸盐含量的日变化规律,并着重从硝酸盐吸收和同化的角度综合阐述了光照影响植物硝酸盐累积的机理。
Nitrate is a type of substance easily accumulated in vegetables, especially in leaf vegetables, and poses serious health hazard if ingested excessively. Light is one of the most important environmental factors that influence nitrate content in plants. This review summarized the effects of light on nitrate accumulation in vegetables from the aspect of light intensity, light quality and light duration respectively, expatiated the daily variation in nitrate content in vegetables under traditional lighting mode, and summarized the effect mechanism from the aspect of nitrate absorption and assimilation.
