Adaptação de novos genótipos de videira para o fortalecimento da vitivinicultura no Nordeste brasileiro

Abstract

Vitiviniculture is an activity that has great importance for the Brazilian economy, providing employment and income generation. Brazil faces several challenges for the production of grapes and wines that are of good quality, thus meeting the requirements of the market. The present work had the objective of characterizing and evaluating the phenological and productive behavior of 10 grapevine cultivars cultivated in Agreste Meridional de Pernambuco. The experiment was installed in the Municipality of Brejão. Ten grape cultivars were studied for the elaboration of fine wines: Muscat Petit Grain, Merlot Noir, Carbenet Sauvignon, Petit Verdot, Pinor Noir, Malbec, Viognier, Sauvignon Blanc, Syrah and Chardonnay. The experiment was carried out in a vineyard with approximately three years and ten months of age, in a straightedge conduction system, spaced 3.0 x 1.0 m and irrigated by micro sprinkler. The experimental design was in randomized blocks with four replicates and plots constituted by eight plants. The phenological characterization, the thermal requirement, ravaz index, estimated yield (kg / plant), number of bunches per plant, physical and chemical characteristics of the curds of the different cultivars were evaluated in the different subperiods of the crop by means of visits weekly to the experimental area. Two plants of each cultivar were marked by block for the monitoring of phenology. The cultivar Muscat Petit Grain (120 days) presented a shorter cycle, being the earliest cycle, the highest cycle was for the Viognier and Cabernet Sauvignon cultivars. In relation to the production, the cultivars Malbec and Petit Verdot presented good physicochemical characteristics that consequently influence the quality of the wine, indicating also good adaptation in the study period and potential for the studied region.
