| Abstract:
Three packaging treatments, namely, polythene, polythene + KMnO4 and no packing, and eight chemical treatments, namely, NAA 100, 200, 300 ppm, BA 5, 10, 15 ppm, water dip and control were tried on Keshar variety of mango. Total weight loss in 20 days storage period was the maximum in fruits kept open, followed by polythene alone and it was the minimum in polythene + KMnO4. The fruits treated with NAA were comparatively firmer and showed slower colour development and had lesser total weight loss than did the BA treated fruits. The fruits kept in open completed ripening within 12 days storage period whereas the fruits packed either in polythene or polythene + KMnO4 remained unripe. At 20 days storage, the fruits treated with chemicals and packed were fully ripe with attractive colour, good appearance and pulp quality whereas, the fruits kept without packing became over ripe with shrivelled skin and unpalatable pulp. These fruits also lost their marketable quality at 16 days storage period. Between two chemicals, NAA was found more effective in checking ripening process than BA. The shelf-life of mango fruits could be effectively prolonged by about 4 to 8 days by treating them with NAA 200 ppm and packing in polythene or polythene + KMnO4. | |
