Conteúdo: The São Francisco Valley, Northeast Brazil, is one of the most important wine regions with tropical conditions in the world. lt is located between parallels 8 and 1OoS, with an average annual temperature of 26.5 OC and 3,000 hours of sunshine per year. This work shows preliminary results on physiological and agronomic characteristics of Syrah vines.subjected to the practices of leaf removal and shoot trimming. The physiological and agronomical characteristics evaluated were the following: mass of cluster, mass of canes after pruning, mass of fresh and dry leaves, net photosynthesis (An), stomatal conductance (gs), intrinsic water use eficience (WUEi), leaf area (LA) and specific leaf area (SLA). The treatments did not show difJerences related to net photosynthesis (An), stomatal conductance (gs) and intrinsic water use ejJiciency (WUEi). The initial measurements of leaf area showed no difJerence between treatments. The individual leaf area was initially a.ffected by treatments, but during ripening these e.ffects were not revealed in the experimento Reverse e.ffects were observed for specific leaf area, which proved not to be a.ffected by treatments during the immature cluster phenological phase. The studies should be continued for three more seasons .in order to understand how the canopy management of Syrah, growing in a tropical environment, can injluence the agronomical and physiological plant behavior, and the implications for the quality of grapes and wines.
