Partial rootzone drying (PRD) and regulated deficit irrigation (RDI) has been studied in many wine-producing countries as irrigation techniques, which improves the water use efficiency, vigor control and maturation quality of wine grape production without significant crop reduction. This work aimed to compare leaf starch, reducing sugars (RS) and total soluble sugars (TSS), as well as the activities of cell wall acid invertase (CWAI), vacuole acid invertase (VAI) and citosol neutral invertase (CNI), in PRD and RDI treated vines at the São Francisco Valley (Brazil). Leaves of ?Syrah? and ?Moscato Canelli? grafted in two rootstocks (1103 Paulsen and IAC 572) were sampled throughout the day (8:00, 12:00 and 16:00 h) at the flowering, veraison and ripe fruits at June, July and August/2004, respectively. The RDI treatment induced higher leaf starch and RS contents in ?Syrah? vines. For ?Moscato Canelli? vines there was no significant difference among treatments. At flowering, in June/ 2004, the leaf carbohydrate metabolism was lower, probably due to the phenological stage and to lower temperatures and radiation. On the other hand, leaf carbohydrate contents were higher at veraison in August/2004. Leaf starch accumulation was higher at 16:00 h and TSS and RS contents were higher at 12:00 h. No differences of CWAI, VAI, CNI activities were observed among treatments, except for RDI that induced higher CWAI activity in ?Moscato Canelli?/? 1103 P?. Carbohydrate metabolism in vines was influenced by temperature and phenological stages. More studies are necessary for conclusive results for PRD and RDI influence on vine leaves carbohydrate metabolism.
