Resumo

The experiment was conducted in Aparecida do Rio Doce, Southwest Goiás, during the year 2007 and 2008, to characterize the production of grapevine cv. Niagara Rosada, in different pruning times: (1) 7/9/07, (2) 9/28/07, (3) 3/3/08 and (4) 4/19/08. Variables associated to plant production, evaluation of bunches and berries, leaves at harvest, position of fruitful branch in the yolk, number of clusters/fruitful branch, pH, soluble solids, titratable acidity and soluble solids by titratable acidity ratio related to harvests were analyzed. Time of pruning 3 showed the lowest value of leaves at harvest than the others (6.15 leaves) being not considered large or causing defoliation and loss of productivity. For the evaluation of the position of fruitful branch in the yolk, the highest average was observed at the time of pruning 1, where the yolk of higher transmission frequency of branches with fruit were the ones that have been applied hydrogen cyana mide (3rd to 6th yolk), indispensable in the stimulation of the shoots in grapevines. So it follows that the grapevine Niagara Rosada can be pruned in the four seasons studied in Southwest Goiás, since the evalu ations of clusters and berries were shown to be satisfactory in relation to other regions and rainfall did not affect the final quality of fruits in any period.
