Breadfruit marketing is limited by its rapid ripening and deterioration after harvest; therefore, improved postharvest practices may facilitate breadfruit marketing. This study examined the effect of harvest maturity and 1-methylcyclopropene (1-MCP) on the postharvest quality of ‘Ma’afala’ breadfruit (Artocarpus altilis). Breadfruit was harvested at 13, 15, and 17 weeks after flowering, and half of each harvest was treated with 1 μL⋅L−1 of 1-MCP for 20 hours. During storage, the weight of the fruit, hand feeling, skin color, respiration rate, and ethylene production rate were evaluated every other day until the fruit deteriorated. Compared with untreated fruit, 1-MCP treatment delayed the climacteric respiratory peak by 6 days (65% delay), delayed complete softening by 7 days (63% delay), and increased uniformity in the number of days to the climacteric respiratory peak and complete softening. Skin discoloration was delayed during the earliest harvest period by 5 days (108% delay). Picking breadfruit at early harvest maturity may be useful for preventing discoloration, and 1-MCP may be useful for preventing softening.
