Drastic softening and incidence of diseases are the limiting factors of persimmon postharvest life in Iran. Ultraviolet radiation at hormic doses has been used to control postharvest disease and delay softening in some fruits. Therefore in this study UV-C radiation at the doses of 0 (as control) 1.5 and 3 kJm-2 were applied on the Karaj´ persimmon and the quality attributes and disease incidence were evaluated after 0 1 2 3 and 4 month storage at 1C plus 3 days shelf life. Results showed that both 1.5 and 3 kJm-2 UV-C treatments compared to non treated fruits reduced the postharvest disease incidence of Karaj´ persimmon during storage without any important effect on the fruit attributes such as firmness ethylene production and skin color. Hence applied UV-C light after harvest could increase postharvest life of Karaj´persimmon by disease control but for having suitable firmness it must be integrated with other effective postharvest treatments. However it can be recommended for local markets where the consumer prefers soft persimmon same as Iran.

Abstract

Drastic softening and incidence of diseases are the limiting factors of persimmon postharvest life in Iran. Ultraviolet radiation at hormic doses has been used to control postharvest disease and delay softening in some fruits. Therefore in this study UV-C radiation at the doses of 0 (as control) 1.5 and 3 kJm-2 were applied on the Karaj´ persimmon and the quality attributes and disease incidence were evaluated after 0 1 2 3 and 4 month storage at 1C plus 3 days shelf life. Results showed that both 1.5 and 3 kJm-2 UV-C treatments compared to non treated fruits reduced the postharvest disease incidence of Karaj´ persimmon during storage without any important effect on the fruit attributes such as firmness ethylene production and skin color. Hence applied UV-C light after harvest could increase postharvest life of Karaj´persimmon by disease control but for having suitable firmness it must be integrated with other effective postharvest treatments. However it can be recommended for local markets where the consumer prefers soft persimmon same as Iran.
