硒碘联合生物营养强化规律及硒碘交互作用初步研究

硒和碘是人体重要的微量元素,硒和碘缺乏可能导致人体处于亚健康状态或患多种疾病。膳食是安全、高效的补充硒和碘的方式。目前,对植物吸收两种元素的相关性研究较为匮乏。本试验通过施加一定含量梯度的碘酸钾、硒酸盐,探究番茄、生菜两种作物对硒和碘的吸收能力,以及两种元素吸收的相关性。研究结果表明:番茄植株相比生菜,对无机硒和碘酸钾的富集能力更强;生菜和番茄中,硒和碘的吸收没有显著相关性。

Preliminary Study on Rule of Synergetic Biofortification and Interaction of Selenium and Iodine

Iodine (I) and selenium (Se) are important trace elements for human body, and the lack of I and Se may lead to sub-health or a variety of diseases. Diet is a safe and efficient approach of Se and I supplement. However, there are insufficient studies now focusing on the interaction of I and Se on their uptake in plants. This study was to explore the interaction of I and Se on their uptake in tomato and lettuce and the capabilities of two crops in absorbing I and Se by adding potassium iodate and selenate (inorganic Se) with certain concentration gradients. The results showed that compared with lettuce, tomato had a stronger uptake capability for inorganic Se and potassium iodide (KI). There is no significant interaction on Se and I uptake in lettuce and tomato.
