This experiment was conducted in a vineyard located in the Central - southern region of Parana state, aiming to evaluate different types of pruning on the culture of grapevine cv. Bordô in 2007/08 crop season. We used plants with 6 years of age, trained in trellis system and spaced 3.0 x 1.0 m. The vines were subjected to the treatment of short pruning (spurs with two to three buds), long pruning (branches of five to six buds) and mixed pruning (spurs and branches). The variables were: number of bunches per plant, yield per plant and average mass of bunches. Regarding the number of bunches per plant there were significant differences only for long pruning in relation to the others, as well as for average mass of bunches. For the yield per plant there were significant differences among all treatments and the long pruning had higher yield per plant, being approximately three times larger than the production of short pruning.
