Abstract : In an experiment at Sabour in Bihar, GA3 and Ethrel [ethephon] were sprayed on the fruits in the first week of June 1990 to enhance the ripening and improve the storage life of Amrapalli mango fruits. GA3 at 75 and 50 ppm improved the quality and shelf life of fruits. Ethrel at 500 ppm was very effective in enhancing the ripening and improving the quality in terms of TSS, total sugar, ascorbic acid and B carotene content. Treated fruits also escaped attack by fruit flies. Ethrel at 750 ppm improved the quality of fruits but enhanced fruit drop.
