Seeds of common buckwheat (Fagopyrum esculentum) were soaked in water, in 5, 10 or 20 mg SeVI/L, or 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 Se(VI), (up to 185 ng/g) in comparison to Se(IV), (up to 103 ng/g). In plants obtained from seeds soaked in water, regardless of UV-B levels, the highest content of Se was found in leaves. The content of flavonoids in leaves was 7.8 - 15.9 % and in stems 1.4 – 4.1%.

Four combinations of treatments were utilised: well watered plants with and without Se foliar spraying, and drought exposed plants with and without Se foliar spraying. Water-soluble Se compounds were extracted from potato tubers by water or by enzymatic hydrolysis with the enzyme protease XIV or amylase or a combination of protease XIV and amylase. Extraction was performed using incubation (37°C, 24h) and by ultrasound assisted extraction (300 W), using different extraction times. Se(VI) and SeMet were the main soluble Se species in potato tubers, regardless of the growth conditions.
