Post-harvest Evaluation of Bananas (Musa sp.) Cultivated in the Brazilian Semi-arid Region When Submitted to Cold Storage

This study evaluates the post-harvest quality of fruits of different banana cultivars regarding type of propagation when stored in cold at three different times at constant temperature. The experiment was carried out at the Fazenda Terra Santa in the semi-arid region of northeastern Brazil. We applied a completely randomized experiment in a 6 × 3 factorial, evaluating the post-harvest development of ‘Prata-anã’ and ‘Pacovan’ cultivars, propagated in three different ways and analyzed at three distinct times of storage in the cold. The following fruit quality variables were analyzed: soluble solids, vitamin C content, titratable acidity, and potential of hydrogen (pH). The analysis of variance revealed a significant effect at 1% probability in all sources of variation of analyzed variables of Soluble Solids and pH, for the unfolding treatments × storage time of the analyzed variables Vitamin C and titratable acidity, and for the source of variation treatment of the vitamin C variable. The ‘Prata-anã’ cultivar propagated by rhizome with “ceva” was the most efficient technique of propagation, providing good soluble solids and titratable acidity contents, but with the lowest pH values.
