The objective of this work was to study the effects of Harpin, a bio-activator, and modified atmosphere packaging (MAP) on storage life and quality of cherry tomato (Lycopersicon esculentum Mill. cv. 'Naomi'). Tomatoes grown in greenhouse were treated three times with Harpin. Fruits harvested at light red stage were stored in plastic film materials with different O-2 and CO2 permeabilities and stored at 5-6 degrees C and 90 +/- 5% RH. Changes in the quality parameters were observed during the storage period at 7 day-intervals. Spoilage and maturity was accelerated in normal atmosphere (NA). Disorders were reduced with Harpin and low O-2 and high CO2 during cold storage. Harpin combined with MAP produced better results than MAP alone. Therefore, Harpin and MAP treatments in combination proved effective in delaying ripening and maintaining fruit quality during storage. Harpin slowed the changes leading to quality loss in fruits for, 28 days of storage. Harpin treatment and 50 mu m polyethylene (PE) packaging produced the best result.
