| Abstract:
The paper shows the results about the environmental adaptability of Pinot noir clones cultivated at different altitudes. The trial was carried out for 3 years on 7 years old vineyards planted with French and Italian Pinot noir clones grafted on the rootstock SO4. All the vineyards were trained with the Guyot system. The vineyards were located in two Trentino areas (North of Italy) at two different altitudes: 250 and 700 m a.s.l.. The environmental adaptability was evaluated through the study of a model of sugar accumulation rate in berries during during ripening time and through quantitative and qualitative data of grapes at harvest time. There were significant differences between altitudes in must composition and data confirm that Pinot noir variety shows low capacity to adapt to different cultivation areas. The cultivation of Pinot noir must be performed, particularly in restrictive environments, with specific clones in order to obtain high quality production. | |
