The biofortification of crops can counteract human diseases, including selenium (Se) and iodine (I) deficiencies in the diet. Little is known about the effects of combinations of Se and I on microgreens and seeds, or on their accumulation in these tissues. The present study aimed to evaluate Se (SeO , SeO ) and I (I , IO ) biofortification of common buckwheat microgreens and seeds with respect to the effects of the addition of Se, I and Se + I on yield and on physiological and biochemical characteristics.
In combination treatments, microgreens yield (600-800 g m ) was 50-70% higher than for Se and I alone. The respiratory potential also increased by 60-120%. F /F was close to 0.8 in all samples. Se content [0.24 μg g dry weight (DW)] was 50% higher for combination treatments than for Se and I alone. I content was highest for IO treatment (216 μg g DW) and decreased in combination treatments with Se by 50%.
Biofortification of buckwheat microgreens with Se and I should be performed with care because there are synergistic and antagonistic effects of these elements with respect to their accumulation. IO for the biofortification of microgreens should be kept low to prevent exceeding the recommended daily intake of I. © 2019 Society of Chemical Industry.
作物的生物强化可以对抗人类疾病，包括饮食中硒（Se）和碘（I）的缺乏。关于 Se 和 I 的组合对小青菜和种子的影响，或它们在这些组织中的积累情况，人们知之甚少。本研究旨在评估普通荞麦小青菜和种子的 Se（SeO ，SeO ）和 I（I ，IO ）生物强化作用，以及添加 Se、I 和 Se+I 对产量和生理生化特性的影响。
在组合处理中，小青菜的产量（600-800 g m ）比单独使用 Se 和 I 高 50-70%。呼吸潜力也增加了 60-120%。所有样品的 F/F 接近 0.8。与单独使用 Se 和 I 相比，组合处理的 Se 含量[0.24μg g 干重（DW）]增加了 50%。I 含量在 IO 处理中最高（216μg g DW），在与 Se 的组合处理中降低了 50%。
在对荞麦小青菜进行 Se 和 I 的生物强化时应该谨慎，因为这些元素在积累方面存在协同和拮抗作用。为了防止 I 的日推荐摄入量超标，IO 应该保持在低水平，用于小青菜的生物强化。© 2019 化学工业协会。
