摘要：The aim of this project was to study changes in the content of trans -resveratrol in berries and leaves of grapevine ( Vitis sp.) infested by fungal diseases, especially by Botryotinia fuckeliana Whetzel, called as grey mildew, Plasmopara viticola (Berk. & M.A. Curtis) Berl & De Toni, called downy mildew and Uncinula necator (Schw.) Burr, called powdery mildew. In our experiments two white and two blue varieties were used. Contents of trans -resveratrol were determined in healthy and infested leaves and in healthy berries. Infested leaves of white varieties contained more trans -resveratrol than those of blue varieties. The content of trans -resveratrol in berries was lower than that in leaves.
