| Abstract:
The results of a study on local ‘Maruggio’ grapevine are reported. It is among the ancient varietal populations with white grapes located in the Province of Taranto and Bari. The research was carried out on two clones for three years (2000, 2001 and 2002) in Southern Italy, in order to study the evaluation, conservation and valorization of local ‘Maruggio’ grapevine. Ampelographic characteristics of cluster (weight, length, width and number of berries per cluster) and of berry (weight, length, width, seeds number per berry and length of peduncle) were observed at harvest time, according to O.I.V. descriptors list. Must composition (pH, total acidity, tartaric acid, soluble total solids and malic acid) and wine composition (alcohol, total acidity, pH, extracts, ashes alkalinity), were measured at six months of elaboration, according to official analysis methods of Italian Ministry of Agriculture. No statistical differences were evident between the clones of the same cultivar in terms of ampelographic, agronomical and oenological characteristics. The local ‘Maruggio’ vine showed a good yield and a very interesting composition of the grape for oenological purpose, with high value in acidity, excellent value in pH and right content in sugars. | |
