| This study aimed at assessing the cell cycle, and anatomical and biochemical changes that the embryonic axis of Araucaria angustifolia undergoes during development, focusing on the maturation stage. During all development, cells exhibited intense metabolic activity with an abundance of mitochondria, lipid bodies, and vacuolated cells. The continued accumulation of starch and protein was observed by LM and TEM and indicated by spectra of FTIR. Cell differentiation of the procambium was observed with a thickening of the cell wall and the formation of resiniferous ducts. At Stage III and IV, cells exhibited structural changes such as altered or elongated mitochondria and presence of plastoglobules. These results suggest that there is a gradual transition from... |

| 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... |
