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.
Debido al aumento del consumo y las posibilidades de exportación e industrialización, el cultivo de arándanos se ha expandido en Brasil. Dado que Rabbiteye es uno de los grupos de arándanos más cultivados en Brasil, este estudio tuvo como
objetivo evaluar la caracterización productiva del cultivar Bluegem de arándano, grupo Rabbiteye. Las evaluaciones se realizaron con plantas en plena producción durante dos temporadas de cosecha. Se recolectaron datos para las siguientes
variables: distribución de yemas florales y vegetativas, flores abiertas y frutos formados en ramas de dos longitudes diferentes, y número de primordios florales. Los resultados mostraron mayor cantidad de yemas vegetativas y la intercalación entre yemas florales y vegetativas en una proporción de 78% y 48% en brotes largos y cortos, respectivamente. El número total de yemas y el número de yemas florales y vegetativas estuvieron influenciados por la temporada de cosecha y la longitud de los brotes. El número de primordios florales estuvo influenciado por la posición de la yema en el brote, pero no por la temporada de cosecha. El número de flores y frutos, en general, fue mayor en yemas apicales y en brotes largos.
