Abstract : Mature fruit of the cv. Dashehari were harvested in the second week of July and those that sank completely in water (i.e. were fully mature) were ripened as follows: (1) wrapped in newspaper and held in a wooden box at room temperature: (2) as in (1) but together with a vial containing 4 g calcium carbide; (3) as in (2) but with 8 g calcium carbide; (4) dipped in 500 p.p.m. Ethrel (ethephon) solution, dried and packed in newspaper; or (5) as in (4) using 1000 p.p.m. Ethrel solution. Fruit ripened with calcium carbide (generating cetylene) were superior in quality to those ripened with Ethrel; they were more palatable, had a better colour and the contents of TSS, sugars and carotenoids were greater.
