“…(2019) reported that foliar spray application of 21 g Se ha −1 as selenate at grain filling significantly improved shoot biomass and grain yield in wheat. However, De Vita et al. (2017) found no effect of foliar application of selenate at the rates of up to 120 g Se ha −1 on wheat grain yield at the booting stage.…”

Selenium (Se) is an essential micronutrient for human health. Deficiency and suboptimality of Se in human populations are a potential health risk. The reduction of such health risk by biofortification of crops, particularly in wheat has drawn much attention, especially for color-grained wheat as it is rich in anthocyanins and can be used as a major source of antioxidants in diet. Herein, a two-year field study on the purple-grained wheat cultivar (202w17) and common wheat cultivar (Shannong 129) was conducted with soil application (SeS) and foliar spray (SeF) of selenium. Results showed that the SeS increased shoot dry weight and grain yield. Both SeS and SeF enhanced the concentration of organic Se, but the higher concentration of organic Se in the grain of two cultivars was observed in SeF in comparison with SeS. The concentration of organic Se in the grain of 202w17 treated with SeF was approximately 1.5-fold of that in Shannong 129 with SeF. The analysis of Se accumulation in different parts of the plant revealed that 202w17 accumulated more Se in shoots and grain than Shannong 129, and 202w17 had also higher levels of total protein, total free amino acids and anthocyanin in grain than Shannong 129. In addition, SeF significantly increased the concentrations of zinc (Zn), calcium (Ca), magnesium (Mg) in both cultivars, but decreased the concentration of chromium (Cr), cadmium (Cd) and lead (Pd), which phenomenon was more significant in 202w17. Our results indicate that SeS increases plant growth, leading to higher grain yield in two cultivars tested. The purple-grained wheat (202w17) could accumulate more Se in grain and have a higher concentration of orgainic Se in grain than the common wheat (Shannong 129).

“…This suggests that breeders could use molecular markers in breeding and selection for modified Se levels without affecting the grain. For instance, existing evidence shows that increasing Se concentrations in durum wheat grains via foliage dressing does not alter the nutritional profile of pasta during processing and cooking (De Vita et al 2017). Notably, Qse.sau-3D was detected in multiple tissues over two consecutive plant growth cycles in this study, and the associated QTL were continuously expressed during the growth period at Se-deficiency conditions.…”

Background and aims As an essential mineral element, selenium (Se) plays a critical role in human health. Given the low concentrations (<100 mg Se kg-1) of Se in staple crops, the identification of genetic resources with enriched Se, as well as the genes controlling Se concentration, is valuable for the marker-assisted selection of Se-rich varieties. Methods We determined the chromosomal quantitative trait (QTL) for Se concentration over two consecutive plant growth cycles using recombinant inbred lines (RILs) treated with two different concentrations of Se under both field-grown and hydroponic conditions. Results Several QTL for Se concentration were detected across the different treatments. Significant genotypic variation in the tissues of the RIL was found at Sedeficicencycondition. Notably, a QTL located on 3D (interval 214.00-218.00, Qse.sau-3D) affected root length and Se concentration in the leaves and grains, suggesting the existence of the same allele with distinctly different functions. However, the QTL for the agronomic traits measured (plant height, flowering time, and tillering number) and Se concentration were not found to be located on the same chromosomal regions, suggesting that marker-assisted selection for both traits is feasible. Se concentrations in the grains were primarily determined by the mineral transport efficiency of the lines, and the line with the highest Se concentration in the grains always possessed larger, more fibrous root systems. The concentrations of Se in the plant tissues were in the order of: root > stem > grain. Conclusions This is the first study to document a Serich synthetic wheat line, and root structure and Se grain concentration was strongly affected by QTL located on 3D.

“…In previous studies, de Vita et al. () observed no symptoms of toxicity in a wheat field foliar‐sprayed with 400 mg L −1 (120 g ha −1 ) Se(VI), while foliar spraying with 285 g ha −1 Se(IV) even improved the quality of maize grains ( Wang et al., ). Furthermore, no visible symptoms of phytotoxicity were observed in rice plots following foliar spraying with 467 mg L −1 (210 g ha −1 ) Se(IV) ( Ning et al., ), or in apple trees after one‐time foliar spraying with 200 mg L −1 Se(IV) across different growth stages ( Ning et al., ).…”

“…Several studies have shown that foliar spraying of Se in rice, wheat, corn, and grapes is markedly superior to soil application (Boldrin et al, 2013;Chu et al, 2013;Wang et al, 2013b;Zheng et al, 2016). Moreover, spraying date also affects Se uptake and distribution in plants, with a delay in application considered beneficial in increasing Se accumulation in rice and wheat grains as well as in apple fruit (Ning et al, 2013;Deng et al, 2017;de Vita et al, 2017). Interestingly, an opposite trend was observed in blueberries .…”

Consuming selenium (Se)‐rich fruit may play an important role in human health by supplementing Se. The aims of this study were to (1) determine the Se tolerance of pear trees and (2) explore the effects of different Se sources and spraying dates on Se concentrations and transformation of inorganic Se into organic Se compounds in various parts of the pear tree and on fruit quality. Spraying Se(IV) or Se(VI) at a concentration of > 40 mg L−1 resulted in leaf yellowing, marginal withering, and finally leaf abscission. Furthermore, fruit growth and appearance were adversely affected at high Se doses. At the same application stage, Se concentrations in different parts of the fruit were 1.1–4.7 times higher under Se(VI) compared to Se(IV) treatment. For the same Se source, Se concentrations under treatment at the fruit expanding stage were 1.9–2.5 times higher than under treatment at the fruit‐setting stage. Of the total Se in the fruit, 40% accumulated in the juice under Se(IV) treatment and > 70% under Se(VI) treatment. However, regardless of the Se source, the Se in the juice was almost all inorganic, while the transformation of inorganic Se into organic Se compounds was > 80% and 70% in the peel and pomace, respectively. Foliar Se application somewhat improved fruit quality by increasing the concentration of soluble solids. Compared to other species, Se tolerance in pear trees was relatively low. Given the high accumulation of Se and efficient transformation of inorganic Se into organic Se compounds in the peel, consumption of unpeeled Se‐rich pears is recommended.
