Aromatic composition of two Muscat grape cultivars cultivated in two different regions of Tunisia

Abstract

The aromatic composition of two Muscat grape cultivars ('Muscat of Alexandria' and 'Italia') cultivated at two sites in Tunisia were significantly affected by the year of harvest (2001 and 2002). In all cases linalool reached its odor perception threshold in both cultivars grown at both sites. Over the two consecutive years, linalool evoluted inversely to nerol and geraniol. The two muscat cultivars produced fruit with high muscat aroma typicity only at the Tunis site (characterized by semi-arid climate). Under Rjim Maĝtoug conditions (Saharan climate), they showed poor Muscat typicity. Copyright © by The Haworth Press, Inc. All rights reserved.
