  • Distribution of selenium and phenolics in buckwheat plants grown from seeds soaked in Se solution and under different levels of UV-B radiation
    Ožbolt, Ljerka ...
    Seeds of common buckwheat (Fagopyrum esculentum) were soaked in water, sodium selenate (5, 10 or 20 mg SeVI/L), or sodium selenite (10 or 20 mg SeIV/L) solutions. Plants grown from soaked seeds were ... exposed to reduced UV-B radiation, ambient, or enhanced UV-B. The mass fraction of selenium in leaves was much higher in plants obtained from seeds soaked with selenate (up to 185 ngžg) in comparison to selenite (up to 103 ng/g). In plants obtained from seeds soaked in water, regardless of UV-B levels, the highest concentration ofselenium was found in leaves, where the values were between 45 and 66 ng Se/g. In buckwheat leaves 44.5-63.6 mg/100 g d.m. of fagopyrin was found, and in stems 14.3 - 26.4 mg/100 g d.m.; here no influence of seed soaking solutionor UV-B exposure was found. The content of total flavonoids in leaves was 7.8 - 15.9 % and in stems 1.4 - 4.1%.
