Abstract: The effect of genotype and selenium foliar biofortification in the form of an aqueous solution of sodium selenate on the content of total carotenoids, vitamin C and total polyphenols content in the tomato fruits was studied. Field experiment was held in the Botanical garden of the Slovak University of Agriculture in 2014. Two determinant varieties of tomato (Brixol F1 and Uno rosso F1) in the three variants were observed. Foliar application of selenium had a positive effect on the increase of total polyphenol content. The influence of Se biofortification on the content of vitamin C and carotenoids was not detected. Within the followed varieties significant effect of genotype on observed characteristic wasn’t found. Selenium foliar fertilization in dosage 150 g/ha is suitable way of tomato fruits enriching in polyphenols, without negative effect on other antioxidants content.
