Abstract
Mangoes Mangifera indica L ‘Manila’ were subjected to the USDAapproved hot water treatment and then exposed to synthetic air mixtures containing 05 075 or 1 ml l−1 of ethylene for 6 12 or 18 h at 25 °C to induce accelerated ripening After treatment the mangoes were allowed to ripen in air at 24–25 °C The content of 1aminocyclopropane1carboxylic acid ACC and ACC oxidase ACO activity increased in fruit treated with 05 and 075 ml l−1 of ethylene for 6 or 12 h Ethylene production was reduced in fruit treated with 1 ml l−1 of ethylene This was due to the decreased of ACC synthesis rather than to lower ACC oxidase activity Treatment with 05 ml l−1 of ethylene for 12 h was found best for accelerate ripening fruits were fully ripened and edible 3 days after treatment compared to 6–7 days for untreated mangoes
