Resumo

The rootstock can be an agronomic tool to modulate the response of a certain variety and better adapt the crop to the edaphoclimatic conditions. This paper summarizes the first results obtained in a new field trial in which the ‘Monastrell’ variety has been grafted on various rootstocks, including the most commonly used ones (110R, SO4, 1103P) and the new material (M1, M4, RG3 and RG8). The vineyard is located in Santomera (Murcia) and was deficit irrigated at 75% of the total vine needs. During the first year of entry into production of the vines, no significant differences were found at the productive level, although the M4 and RG3 rootstocks were the least vigorous. The RG8 rootstock slightly delayed vine phenological development increasing the pH of the must in particular in comparison with the rootstock of the M series, which were the ones that increased the concentration of grape total soluble solids to a greater extent without affecting grape phenolics. Rootstock SO4 was, however, the one that reduced grapes sugars concentration at harvest the most. The results obtained will be corroborated in the coming years in more adult vines.
