APPLICATION OF BTH AND METHYL JASMONATE DURING THE RIPENING OF GRAPES (VITIS VINIFERA L.) AND ITS EFFECTS ON THE STILBENE CONTENT: PRELIMINARY RESULTS

Pre-harvest treatments of grapevine (‘Monastrell’) with the plant defence response elicitor benzothiadiazole (BTH, 0.3 mM) and methyl jasmonate (10 mM), an important growth regulator, were applied to check whether these compounds could enhance stilbene accumulation in berries at the moment of harvest, due to the interesting health properties of the stilbenes in grapes and wines.
Both compounds were sprayed on clusters at veraison.
Both compounds enhanced the level of stilbenes in grapes, the highest increase being found with the use of methyl jasmonate.
Since a highest presence of stilbenes in grapes could be a protection against mould infection, the application of these compounds could, not only improve the healthiness of grapes, but also limit the use of fungicides.
