Abstract

1-Methylcyclopropane (1-MCP) is an ethylene inhibitor tested for maintaining fruit quality and extending storability of Tommy Atkins mango fruits as an export variety.The fruits were harvested at maturity stage in July 2019 and 2020, immersed in (1-MCP) water solution at 750,1500 and 2250 ppb for 5 minutes besides control fruits soaked in tap water for the same period. Fruits were air dried then cold stored at 8°C ad RH 85-90% for 15,30,45and 60 days. After each storage period fruits were holding to ripe at 20°C for 7 days, At the end of storage period either 8°C and 20°C, fruit quality characteristics (weight loss,decay percentage, firmness and respiration rate, TSS %,and total acidity %) were evaluated. The results evaluated that (1-MCP) at 1500 ppb and storage at 8°C for 45 days was the best treatment for maintaining fruit quality after cold storage and the following ripening period at 20°C.
