Due to the increase in consumption and the possibilities of exportation and industrialization, blueberry cultivation has been expanding in Brazil. Since Rabbiteye is one of the more cultivated groups of blueberries in Brazil, this study aimed to assess the productive characterization of the blueberry cultivar Bluegem, group Rabbiteye. Assessments were conducted with plants in full production during two harvest seasons. We collected data on the following variables: flower and vegetative bud distribution, open flowers and formed fruit in two different shoot lengths, and number of floral primordia. The results showed a greater number of vegetative buds and the intercalation between flower and vegetative buds in a proportion of 78% and 48% in long and short shoots, respectively. The number of total buds and the number of flower and vegetative buds were influenced by the harvest season and the shoot length. The number of floral primordia was influenced by the bud position on the shoot, but not by the harvest season. The number of flowers and fruits, in general, was greater in apical buds and in long shoots.

Palabras clave : flowering; growth; bud position; Rabbiteye; fructification; Vaccinium spp.
