“…The highest concentration of Se in Se enriched plants was found in seeds and leaves while considerably lower concentrations were found in stems and husks in both taxa studied. Similar distribution patterns of Se in common buckwheat plants were observed by Vogrinčič et al (2009), who used a lower concentration of Se for foliar spraying. Higher contents of Se in seeds and leaves than in stems was also observed by Ožbolt et al (2008) in an experiment in which buckwheat was grown from seeds previously soaked in solutions of sodium selenate and sodium selenite.…”

“…Foliar spraying of buckwheat plants with a solution of sodium selenate at the beginning of fl owering has a benefi cial effect on the Se content in all above-ground plant organs, such as seeds, leaves, and stems (Smrkolj et al 2006b, Vogrinčič et al 2009). As plants are the main source of dietary Se, metabolism of Se in plants is important for the Se nutrition of humans and animals.…”

-In fi eld experiments, tartary buckwheat and hybrid buckwheat were foliarly sprayed with an aqueous solution of sodium selenate (20 mg Se L -1 ). In treated plants, the selenium content was signifi cantly higher than in controls, irrespective of the plant part and taxon of buckwheat. The highest average Se concentrations in hybrid and tartary buckwheat were found in seeds. The main Se species found in seeds was Semethionine. Selenium-sprayed plants had higher photochemical effi ciency of photosystem II in both taxa and higher electron transport system activity in hybrid buckwheat, suggesting a positive effect of Se on physiological characteristics. Because of the concentration of Se in both buckwheat taxa and selenomethionine as the dominant species of Se, Se-enriched buckwheat is a potential source of dietary Se for animals and humans.

“…The highest Se content among different parts of common buckwheat was observed in F2 and H treatments, F1 and F2 had higher Se accumulations in the parts of common buckwheat plant in comparison to F0 treatment, respectively (Table 2). Chilimba et al (2012) found that maize grain Se concentration increased by 11-33 μg Se/kg for each g Se/ha soil applied (0, 1.5, 3.0, 4.5 and 6.0 g Se/ha) under field condition, Vogrinčič et al (2009) also suggested that common buckwheat have a high Se-rich potential. In our study, Se content of the common buckwheat plant increased with the rising Se rates of soil application.…”

“…Single effects of foliar spray or application via root of Se on grain Se concentration and yield have been recognized in buckwheat under controlled conditions (Vogrinčič et al 2009).

“…Vogrinčič et al (2009) reported that the mass fractions of Se in all plant parts increased and were approximately 50-to 500-fold higher according to the plant part after foliar fertilization with sodium selenate, suggesting that common buckwheat is a proper food crop for Se-rich food, especially in the Se-deficiency area. However, the interaction effect and relationship of foliar and soil application of Se on crop Se uptake are still not fully understood especially in common buckwheat under field conditions.…”

Selenium (Se) is a significant trace element for human and livestock animals because of its physiological functions. Se in plants, especially in the crop plants, is treated as a critical dietary source. The effects of foliar spray together with soil application of Se on Se uptake, distribution in common buckwheat (Fagopyrum esculentum M.) plants were discussed in this study. The results showed that both foliar spray and soil application of Se increased Se uptake in common buckwheat significantly (P < 0.05). The highest Se content was observed in leaves (113.37-690.75 μg/ kg), followed by roots (28.98-283.78 μg/kg), grains (26.49-135.89 μg/kg) and stems (23.19-86.80 μg/kg). Se content in grains had the highest correlation coefficient (0.827 and 0.845) with soil Se application treatments. Grain yield of F1 (5 g Se/ha for foliar spray) was 3.65% and 10.25% higher than that of F0 (0 g Se/ha for foliar spray) in two study years, respectively. Under soil Se application conditions, mean grain yields fluctuated from 2890.5-3058.6 kg/ha, 2966.4-3352.8 kg/ha in 2012/2013, respectively. These results indicated a significant interaction effect of foliar spray Se and soil Se application on Se accumulation in common buckwheat. Appropriate Se application might improve common buckwheat grain yield.

BACKGROUND As a potential selenium‐enriched crop, it is of great significance to study the selenium application of Tartary buckwheat. Therefore, to study the effects of selenium application concentration, variety, selenium application period and method on the grain selenium content and yield of Tartary buckwheat, an orthogonal experimental design was used to carry out field experiments in the Jinzhong and Northwest Shanxi ecological regions at the same time. Heifeng 1 and Jinqiao 2 were applied at the branching stage and flowering stage in the Jinzhong, and Heifeng 1 and Jinqiao 6 were applied at the early flowering stage and peak flowering stage in the Northwest Shanxi with different concentrations of sodium selenite (0, 1.37, 2.74, 5.48, 8.22, 12.33, 18.495, 27.7425 g hm−2) by foliar spraying and soil application. RESULTS The results showed that the selenium content in Tartary buckwheat grains was positively correlated with the selenium application concentration and increased with increasing selenium application concentration, while the yield of Tartary buckwheat first increased and then decreased with the selenium application concentration. The grain selenium content and yield of Tartary buckwheat were affected by the selenium application concentration, variety and application method. CONCLUSION The most effective selenium biofortification program was spraying 2.32 g hm−2 sodium selenite on the leaves of Heifeng 1 at the early flowering stage in the Jinzhong. In the Northwest Shanxi, spraying 11.01 g hm−2 sodium selenite on the leaves of Jinqiao 6 at the flowering stage was the most effective selenium biofortification program. © 2022 Society of Chemical Industry.
