Description
Summary:The objective of this work was to characterize the blueberry (Vaccinium spp.) cultivar Climax, Rabbiteye group (Vaccinium ashei Reade). In order to achieve that, a survey with blueberry plants (cultivar Climax), in full production, was conducted during the 2012/13 and 2013/14 seasons in the mesoregion of Pelotas, Rio Grande do Sul State, Brazil. Data regarding the distribution of flower and vegetative buds on branches of two lengths (long and short) was collected. Another evaluation, considering three positions of flower buds in the branch (apical, medial and basal), the number of flower primordia, open flowers and fruits formed was performed. Data were subject to ANOVA and, when significant, the averages were compared using either the F or Tukey’s HSD test (p ≤ 0.05). The results demonstrate the presence of flower buds intercalated with vegetative ones. The total number of flower and vegetative buds, flower primordia, flowers and fruits was influenced by the length of the branch. Likewise, the position of the bud on the branch affected the results, with a greater number of flower primordia on the basal, a greater number of flowers on the medial and a greater number of fruits on the apical portions of the branches.
