Abstract : The effect of different treatment; potassium permanganate, hot water treatment under 50°C for 30 min. and shrink film addition to control on storage life of mango cultivars Hindi Be-Besennara (early ripe) and Alphonse(mid season) under three low temperature 8, 10 and 13°C and R.H. (80-85%) for 30 days was investigated. The quality characteristics such as decay, shelf life, firmness, weight loss, T.S.S., titratable acidity, ascorbic acid, reducing and total sugars were studied at an interval of 6 days during storage. However, the treatment shrink film at 8°C was the most effective in keeping storability of the two cultivars and this reflect on the mean performance physical and chemical parameters in the two seasons for the two cultivars. It was found that keeping quality in low temperature and decreased with increasing temperature degree. Whereas, hot water treatment take the same trend with control in the high contain of T.S.S., acidity, reducing and total sugars and low content in V.C. All treatments and control had no shelf life in 24 and 30 days in 13°C. Shrink film had no decay till the 24 days under three storage temperature.
