Abstract

Combining the knowledge that Plasmopara viticola causes considerable damages to Vitis vinifera L. worldwide production and that stilbenes have a regulatory influence on Plasmopara viticola - grapevine interaction, this study compares infection time course and stilbenes production in leaves and berries of ten different clones of 'Cabernet Sauvignon'. Following increasing infection rates, different stilbenes were produced and accumulated in leaves and berries of the same clone. Higher absolute values were found in leaves, where trans-resveratrol reaches up to 8 µg g-1 fw and ɛ-viniferin up to 30 µg g-1 fw while in berries, the values accumulated only up to a maximum of 3 µg g-1 fw of trans-piceid and 1,5 µg g-1 fw ɛ-viniferin
