We investigated the effect of selenium form and dose on the total glutathione and non-protein -SH group contents in the edible spinach (Spinacia oleracea L.) and ground tomato (Lycopersicon esculentum Mill.) plants. Our experiments were carried out in a hydroponic culture. Selenium was added to the culture medium in its selenite (Na2SeO3 x 5H2O) and selenate (Na2SeO4) forms. Regardless of the selenium form, we observed an increase in the non-protein thiol content. The non-protein -SH group content depended on the form and dose of selenium as well as on the organ and plant species. Regardless of the selenium form, a higher content of non-protein -SH groups were found in the spinach biomass than in the tomato biomass. Selenite contributed to a larger accumulation of non-protein -SH groups in the roots, whereas selenate contributed to their accumulation in the shoots
