AB The effect of an exogenous grape berry application of methyl jasmonate (MeJA) on the enhancement of the in vivo resveratrol production was tested. MeJA is a plant volatile that acts as an important intracellular regulator mediating diverse developmental processes and defense responses. A treatment with MeJA spray solution was performed on clusters of Vitis vinifera cv. Barbera grafted onto 3309 C rootstock under drought stress condition and regular water supply and at fruit set, veraison, and ripening. Cumulative MeJA treatments significantly increased berry resveratrol and ε-viniferin production at ripening. Water stress did not affect stilbene synthesis.
