Abstract

Background and Objectives With the increasing interest for the development in the cultivation of persimmon, there is neither suitable technology nor enough information about the postharvest behavior and the storability of this fruit in many countries, such as Iran. Softening, chilling injury, and the occurrence of different diseases are the limiting factors for the postharvest life of persimmons fruits during cold storage. Ultraviolet-C (UV-C) light radiation has recently been suggested in controlling the decay and reducing the chilling injury of some fruits. Therefore, this study was conducted to evaluate the effects of UV-C treatments with different doses on alleviating chilling injuries and maintaining the qualitative attributes of persimmon fruits during storage. Materials and Methods The persimmon fruits cv. `Kashan´ were harvested from a commercial orchard near Kashan city. UV-C treatments were carried out at 0 (as control), 5 minutes irradiation from 15 and 30 cm distance with 3. 2 and 0. 8 kJm-2, and 10-minute irradiation from 15 and 30 cm distance with 16. 4 -2 and 4. 1 kJm. After 1, 2, 3, and 4 months, fruits were removed from storage and chilling injury indices, polyphenol oxidase (PPO) activity, and some quality attributes were measured. Results The effect of UV-C treatments on weight loss, chilling index, electrolyte leakage, lipid peroxidation, and PPO activity was influential during storage. High weight loss percentage (6. 84) and chilling symptom (40) were observed in irradiated fruits with 16. 43 kJm-2 and a low level of the mentioned parameters was seen in 3. 2 kJm-2 treatment. A high level of electrolyte leakage (80. 49) and lipid peroxidation (1. 78 nM g-1 FW) were detected in treated fruits with 4. 1 and 16. 43 kJm-2 and a low level of the above parameters was observed in the non-treated and treated fruits with 3. 2 kJm-2. The application of UV-C with a high dose increased PPO activity (9. 7 u gr-1 FW) in comparison to other treatments during storage. Discussion Our results suggest that the application of UV-C irradiation at a low level after harvest could increase the postharvest life of `Kashan´ persimmon by controlling chilling injuries and preserving Background and Objectives With the increasing interest for the development in the cultivation of persimmon, there is neither suitable technology nor enough information about the postharvest behavior and the storability of this fruit in many countries, such as Iran.
