Effect of maturity stages and anti-fungal treatment on post-harvest life and quality of mandarin oranges stored in a cellar store, 1995/96.

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 November 1995 and stored for 120 days on bamboo shelves in an underground cubic storage structure at Lumle (1665 m above sea level), Sigana (1350 m) and Lohi (600 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 (largely due to Penicillium italicum) were recorded at fortnightly intervals following treatment. Fruit TSS content increased significantly as storage time (at Lumle and Sigana) and percentage yellowness (at all 3 sites) increased. Significant negative relationships existed between TA and both length of storage period and percentage yellowness. Percentage fruit weight loss increased significantly as storage time increased, but final average w

eight losses were greater at Lohi (16.4%) than at Sigana and Lumle (13.4 and 12.7%, respectively). Dipping treatments significantly reduced percentage fruit rotting, the most effective treatment being benomyl + paraffin wax.
