SOUZA, Florisvaldo Gama de et al. Postharvest quality of fruits from different mangabeira clones (Hancornia speciosa Gomes). Ciênc. agrotec. [online]. 2007, vol.31, n.5, pp.1449-1454. ISSN 1981-1829. http://dx.doi.org/10.1590/S1413-70542007000500027.
This work aimed to evaluate the postharvest quality of fruits from different mangabeira clones (Hancornia speciosa Gomes) for industrialization and/or in natura consumption. Fruits were analyzed from the following mangaba tree clones: Ipojuca 3, 4 and 5 (IPJ 3, 4 and 5); Nizia Floresta 1, 6 and 8 (NIF 1, 6 and 8); Parnamirim 11 (PAR 11); Rio Tinto (RIT 7); Extremoz 1 (EXT 1) and Touros 48 (TOU 48), grown as part of the germoplasma bank at Mangabeira Experimental Station of EMEPA - Empresa Estadual de Pesquisa Agropecuária da Paraíba, located at João Pessoa-PB, Brazil. Mangabas, were manually packed into polystyrene lined plastic boxes and transported to the Postharvest Physiology and Technology Laboratory at Embrapa Agroindústria Tropical, at Fortaleza-CE. At Embrapa, fruits were analysed for chemical and physical-chemical quality parameters. Quality parameters analyzed were weight, length and diameter, texture, number of seeds, yield pulp and skin, pH, total titratable acidity (TTA), total soluble solids (TSS), TSS/TTA ratio, total vitamin C, total soluble sugars, reducing sugars, phenols as dimers, oligomers and polymers. Statistical analysis of variance revealed significant differences for all characteristics through Test F. Fruits from all the clones showed superior quality when compared to standards designed by MAPA on I.N. nº 1 from 07/01/2000. Greatest industrial yields were observed for clones IPJ 3 and NIF 6. Clones RIT 7 and TOU 48 showed greater postharvest life suggesting potential for in natura consumption.
