Effects of Foliar Selenite on the Nutrient Components of Turnip (Brassica rapa var. rapa Linn.)

Abstract

We administered foliar applications of 50, 100, and 200 mg L−1 selenium (Se, selenite) on turnip (Brassica rapa var. rapa Linn.) and detected the changes in the main nutrient components in fleshy roots. Results showed that the foliar application of Se (IV) significantly increased the Se content in turnip, and Se (IV) positively affected the uptake of several mineral elements, including magnesium, phosphorus, iron, zinc, manganese, and copper. Se (IV) treatments also improved the synthesis of protein and multiple amino acids instead of crude fat and total carbohydrate in turnip, indicating that the foliar application of Se (IV) could enhance Se biofortification in turnip and promote its nutritional value. We recommended 50–100 mg L−1 Se treatment for foliar application on turnip based on the daily intake of Se for adults (96–139 μg person−1 day−1) and its favorable effects on the nutrient components of turnip.

Selenium and Nano-Selenium Biofortification for Human Health: Opportunities and Challenges

“…The most important nutrients that have been investigated in several biofortification studies include calcium [106], iron [92,107], copper [108], zinc [109][110][111], iodine [29,92], potassium [112], and selenium [66,113]. The use of Se fertilizers is one of the most common methods for Se-biofortification of several crops [105], such as rice [113][114][115], maize [116,117], wheat [92,111,118], cowpea [119], potato [85,120], carrot [90,121], turnip [122,123], shallot [124], beans [125], lettuce [91,126], basil [127], strawberry [32,33], and apple [128,129]. Edible plants that have been biofortified with Se [105] or livestock fed selenium-enriched alfalfa [25,130] are used to support human health as reported by the Finnish experience in biofortification with Se through fertilizers.…”

“…It is also important for photosynthesis and respiration (Kim and Guerinot, 2007). Li et al (2018) reported that when Se is applied to the plants, it increases the concentration of iron. He et al (2007) also reported that application of Se in lettuce had increased mineral content.…”

Advances in selenium supplementation: From selenium-enriched yeast to potential selenium-enriched insects, and selenium nanoparticles

“…Although several studies have been conducted worldwide ( Alfthan et al., 2015 ; Grant et al., 2007 ; McLaren and Clucas, 2006 ; Yan et al., 2021 ; Yuan et al., 2022 ), this strategy is mainly used in Finland, where the problem of Se deficiency in soil is widespread. Biofortification can be carried out in different ways, such as application on leaves ( Graham, 2018 ; Kápolna et al., 2007 ; Ros et al., 2016 ; Xiong et al., 2018 ) or directly in the ground ( Broadley et al., 2010 ; Larsen et al., 2006 ; Ros et al., 2016 ).…”
