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. |

O nitrogênio atua positivamente sobre o fluxo de biomassa das forrageiras, porém a magnitude das respostas são variadas. Objetivou-se avaliar os parâmetros morfogênicos do capim-massai manejado sob pastejo com ovinos e adubado com nitrogênio (0; 400; 800 e 1200 kg de N ha-1ano-1) num delineamento inteiramente casualizado, com medidas repetidas no tempo. A taxa de alongamento foliar foi incrementada pelas doses de N, de 2,32 para 5,14 cm?perf-1?dia-1 nas doses de 0 a 1200 kg de N ha-1?ano-1, porém pouca alteração foi verificada para referida variável ao longo dos ciclos de pastejo. A taxa de alongamento das hastes foi influenciada pelas doses de N, porém mostrou-se semelhante com os ciclos sucessivos de pastejo. A taxa de senescência foliar anterior e posterior não foram influenciadas pelas doses de N, nem tampouco diferiram entre os ciclos de pastejo. A adubação nitrogenada favorece o fluxo de biomassa do capim-massai até a dose de 1200 kg de N?ha-1?ano-1. Os ciclos de pastejo exercem pouca alteração nos parâmetros morfogênicos do capim-massai. Morphogenesis in massai grass fertilized with nitrogen and grazed by sheep. Abstract: The Nitrogen acts positively on biomass flow of plants, but the response intensity is variable. To evaluate the biomass flow of massai grass managed under grazing by sheep and fertilized with nitrogen (N) (0; 400; 800 and 1200 kg N ha-1year-1) in a completely randomized design with repeated measures in time this work was carried out. The leaf elongation rate was increased with the N fertilization levels from 2.32 to 5.14 cm?perf-1?day-1 for rates from 0 to 1200 kg N ha -1?year-1, but little change was observed for this variable throughout the grazing cycles. The culm elongation rate was influenced by N levels, but was not influenced by grazing cycles. The leaf senescence rate before cut and after cut was not influenced by N levels and was not influenced by grazing cycles. The nitrogen fertilization provide positive responses to the biomass flow of massai grass.
