Abstract : A study was conducted to evaluate the influence of 1-methylcyclopropene (1-MCP) on postharvest conservation of exotic mango (Mangifera indica) fruits of cultivars 'Rosa', 'Jasmim' and 'Espada', harvested at mature-green and pre-climacteric maturity stages, from an orchard in Areia, Paraíba State, Brazil. Fruits from each cultivar and maturity stage were treated in sealed chambers with 100 ppb 1-MCP for 24 h. Fruits were stored at room temperature (23±1°C) and 80% RH for 16 days. Fruit weight loss, total soluble solids (TSS), total titratable acidity (TTA), skin colour (1-7 scale) and external appearance (1-5 scale), were evaluated. The results show that 1-MCP was capable of delaying ethylene-induced ripening processes for all mango cultivars tested. Mature-green 'Rosa' and 'Espada' mangoes treated with 1-MCP presented lower weight losses, while maintaining TSS, TTA and better external appearances. For 'Jasmim' cultivar, by the end of evaluation period, better external appearance was more evident for pre-climacteric fruits.
