Responses of Musa AAA Berangan to 1-methylcyclopropene

1-methylcyclopropene (1-mcp) is an inhibitor of ethylene perception and has been shown to delay the ripening of cavendish bananas. nevertheless, no work has reported the delay in the ripening of local bananas using 1-mcp. the objective of this study was to examine the responses of berangan banana to 1-mcp applied at the ripening stage 1 (mature green) and ripening stage 2 (partially ripe). in experiment i, 1 μl l^-1 of 1-mcp was applied to mature green stage banana for 0, 2, 4 and 6 h, followed by ripening initiation using 10 g cac2 kg^-1 fruit for 24 h. meanwhile, in experiment ii, the fruits were partially ripened using 10 g cac2 kg^-1 fruit for 24 h, followed by exposing them to 1 μl l^-1 of 1-mcp for 0, 2, 4 and 6 h. exposing mature green berangan banana to 4 h of 1-mcp delayed degreening, retained flesh firmness and soluble solids concentration. on the contrary, exposing 1-mcp to the partially ripened banana fruit failed to delay both degreening and ripening processes. fruit of both experiments ripened normally after the 1-mcp treatment, with more rapid ripening processes in partially ripe than mature green fruit.
