Ethylene biosynthesis and respiration in mango fruits during ripening.

Fruits of mangoes cv. Amrapali and Dashehari, harvested mature but green, produced measurable amounts of ethylene during postharvest ripening. The ethylene production did not follow a climacteric pattern. During ripening two ethylene peaks were recorded, one at 2-3 days after harvest and the other at 6-7 days after harvest. Ethylene-forming enzymes and ethylene production declined whereas ACC content increased in some tissues (e.g. peel, outer mesocarp and inner mesocarp) with the progress of ripening in both the cultivars. Embryo (stone) also produced measurable levels of ethylene, which increased throughout ripening. Peel of the fruit showed the highest levels of ethylene and ethylene-forming enzymes and less ACC accumulation than outer and inner mesocarp at the mature green stage. The inner mesocarp showed less ethylene-forming enzyme activity and high ACC accumulation as compared to peel during the ripening process. Respiration increased until 6-7 days after harvest and then declined.
