In current study, we used skins ‘Italia’, ‘Benitaka’, ‘Muscat Alexandria’, ‘Flame Muscat’, ‘Rosario Bianco’, Rosso’, ‘Red Rosario’ at véraison st...

• Water regime and climatic conditions affect aroma composition of “Muscat Alexandria”. Negative relationships between total volatiles vine yield were observed. Pre-veraison water deficits increased glycosidycally-bound compounds. No stress during pre-veraison free Seasonal effects predominated over those regimes on grape aromas. Irrigation in relation to the environmental aromas are still unkn...
