Abstract

RIBEIRO, Thalita Passos et al. Quality and bioactive compounds in fruit of foreign accessions of mango conserved in an Active Germplasm Bank1. Rev. Ciênc. Agron. [online]. 2015, vol.46, n.1, pp.117-125. ISSN 1806-6690.  https://doi.org/10.1590/S1806-66902015000100014.

The aim of this study was to characterise the quality and levels of bioactive compounds in the fruit of 22 foreign accessions of the mango belonging to the Active Germplasm Bank of Embrapa Semiárido. Sixty fruits from each of the accessions: Florigon, Haden, 65, Irwin, M 13269, Momi-K, Scuper Many, Simmonds, Tommy Atkins, Van Dyke, Winter, Zill, Amrapali, Olour, Aplle DCG 406, Mon Amon DCG 407, Black Java, Kensington, Chené, Manila, Manzanillo and Maya, were harvested upon reaching physiological maturity, one half being analysed when harvested and the other half stored at ambient temperature (25.4 ± 2.9 ºC and 41 ± 9% RH) until ripe. The experimental design was completely randomised in a 22 x 2 factorial (accession x maturity stage), with three replications of ten fruits. The accessions Chene, Momi-K and Van Dyke stood out for their physical attributes: weight, length, diameter and firmness of pulp, and for their good post-harvest conservation. The accession Amrapali was different because of its high levels of soluble solids, total soluble sugars, starch, ascorbic acid and carotenoids, suggesting a high potential for insertion into a breeding program aimed at the quality of the mango.
