OLIVEIRA JUNIOR, LUIZ FERNANDO GANASSALI DE et al. PROTOCOL FOR HARVESTING ‘BRS PRINCESS’ BANANA FRUITS. Rev. Bras. Frutic. [online]. 2017, vol.39, n.1, e-316.  Epub 30-Mar-2017. ISSN 0100-2945.  http://dx.doi.org/10.1590/0100-29452017316.

The aim of this study was to develop a protocol to determine the ideal harvest time for ‘BRS Princess’ banana, using the number of aborted bracts. The bananas were selected according to the number of aborted bracts since the flowering until the time of harvest, yield clusters with 90, 95, 100 and 105 aborted bracts. The physical and chemical analyzes were performed every 3 days on fruits: soluble solids, titratable acidity, weight loss, length and diameter, pH, firmness, skin color (CIELab) and pectin enzyme activity. The statistical design was completely randomized in a 4x5 factorial, with 4 points and 5 periods of harvest analysis and data were evaluated using analysis of variance and regression. For all parameters, fruits harvested at 90 and 105 aborted bracts had unwanted changes in its metabolism when compared to the other treatments, while fruits harvested at 95 and 100 aborted bracts had the best post-harvest characteristics. This method was effective in determining the point of harvest in ‘BRS Princess’ banana fruits, since it allows to obtain fruit quality after storage, and is a simple and objective method.
