Effect of selenium (Se) was studied in soybean (Glycine max (L.) Merr.) cv. Olna in Ljubljana, Slovenia. Se was added to plants as foliary spraying. Quantum yield of photosystem II (PSII) and respiratory potential measured as ETS activity of mitochondria were measured two times in the growing season. Respiratory potential was higher in young plants compared to mature plants. Se induced the lowering of respiratory potential. Addition of Se had no effect on quantum yield of photosystem II.

The transformation of selenium (Se) in buckwheat sprouts grown from seeds soaked in various Se solutions was investigated. The extraction procedure was optimised by (a) using optimal extraction media (water, phosphate buffer, 0.1, 0.2, 0.3 M HCl, the enzyme protease alone or in combination with cellulase, amylase or lipase), and by (b) optimising the ratio between sample and enzyme. Optimal extraction efficiencies were obtained by hydrolysis with 0.3 M HCl and protease. Selenate, Se-methionine and selenite (traces) were detected in all supernatants, regardless of soaking solution.
