Vitis vinifera L. cv. Merlot clone R3, grafted on 3309 C (lime-susceptible) rootstock, was grown in pots on a noncalcareous and a calcareous soil. The aim of the experiment was to check the effect of lime stress conditions on chlorosis, grape yield, technological parameters and stilbene (resveratrol, piceid, piceatannol, ε-viniferin) concentrations in grapes. Lime-induced chlorosis decreased grape yield per plant to a very high extent, as a result of a reduction of cluster and berry size. Technological grape parameters such as soluble solids, pH, anthocyanins, increased under lime stress over the control, whilst titratable acidity was not affected. All the tested stilbenes, being stress compounds, increased in the grapes of chlorotic vines.
