Postharvest Ripening and Shelf Life of Mango (Mangifera indica L.) Fruit as Influenced by 1-Methylcyclopropene and Polyethylene Packaging

The mango (Mangifera indica L.) is a climacteric and highly perishable fruit that requires specialized postharvest handling to extend its storage life. The study was undertaken at Melkassa Agricultural Research Center (MARC) to evaluate the influence of 1-Methylcyclopropene (1-MCP) and polyethylene packaging (PP) on postharvest storage of mango. Fruits of two mango cultivars namely ‘Apple’ and ‘Kent’ were harvested at green-mature stage and were treated with gaseous 1-MCP (100 or 500 nLL-1) in closed plastic containers for 18 hours and then individual fruits were either packaged with perforated polyethylene bags or kept without packaging. They were stored up to 21 days under ambient condition at temperature of 25.7 ±2.6oC and relative humidify of 66.1±11.8%. Treatments were laid out in factorial arrangement in RCBD with three replications. The physiological weight loss (PWL), peel color change, firmness, juice content, total soluble solids (TSS) and titratable acidity (TA) were significantly (
