Abstract : The experiment was conducted at Horticulture Section, Department of Agricultural Research (DAR), Yezin from May to June 2006. Packaging treatments with imperforated polyethylene bag and 3, 6, 9 pores-perforated polyethylene bags (T2 to T5) significantly reduced weight loss percent for STL and YK cultivars until 40 DAS. No shrinkage symptom was observed in both mango cultivars packaged with perforated and imperforated bags. Nonetheless, shrinkage was observed in control fruit (T1 non-packaging) at 10 DAS and onwards. Fruit stored in imperforated bags (T2) were observed to be maintained the fruit firmness up to 40 DAS. However, perforated polyethylene packaging treatment indicated that the hardness of fruit gradually decreased with increase in DAS throughout the storage period. The least colour development of STL and YK was observed in imperforated packaging (T2) and it was also significantly less than those of other treatments. The results revealed that fruits in imperforated packaging retained the fruit still olive green up to 30 DAS. Fruit kept in 9 pores perforated packaging (T5) indicated the highest sweetness level compared to T1 and T4 treatments. The body rot and stem end rot of STL and YK fruit packaged by imperforated bag (T2) showed the minimum severity among the treatments. Hot water dipping significantly reduced the body rot of both cultivars in all treatments at 40 DAS. However, stem-end rot could not be significantly reduced by hot water except STL fruits in T1 and T5.
