Effect of maturity stages and anti-fungal treatments on post-harvest life and quality of mandarin oranges stored in a cellar store, 1994/95.

Mandarin (Citrus reticulata cv. Suntala) fruits of 5 different maturity classes (mature green, 75% green, 50% green, 25% green and 100% yellow) were harvested in December 1994 and stored for 120 days on bamboo shelves in an underground cubic storage structure at Lumle (1675 m above sea level), Sigana (1250 m) and Lohi (650 m), Nepal, after the following treatments: (1) benomyl at 1000 ppm, (2) 6% paraffin wax, (3) benomyl + paraffin wax, or (4) untreated (control). Total soluble solids (TSS), titratable acidity (TA), weight loss and percentage fruit rotting were recorded at fortnightly intervals following treatment. Fruit TSS content increased significantly as both storage time and percentage yellowness increased. In fruits stored at Lumle and Lohi, a significant negative relationship existed between TA and length of storage period, while a significant positive relationship existed between TA and percentage yellowness. Percentage fruit weight loss increased significantly as storage time increase

d, but average weight losses were greater at Lohi (14.7%) than at Sigana and Lumle (13.3 and 9.5%, respectively). Dipping treatments significantly reduced percentage fruit rotting, the most effective treatment being benomyl + paraffin wax.
