Shelf life of cucumber fruits is dependent on the preharvest conditions prevailing during the growing season as well as on storage conditions. The aim of this study is to investigate the effects of growing factors in soilless culture on postharvest performance of cucumbers. Test plants were grown in bags with 8 litres of rooting volume filled with perlite. The factors examined were: nutrition system (open and closed), bag type (vertical and horizontal bags containing one or two plants per bag, respectively) and cultivar (Afrodit, Efes and Rawa). Fruits of the plants from each treatment were packed in PE bags and stored for 21 days at 13 deg C and 85-90% RH. During storage, weight loss, changes in colour, chilling injury symptoms and general appearance scores were determined at three-day intervals, and fruit firmness was measured weekly. Nutrition system affected weight loss only during the first 9 days of storage, being lower for fruits from the open system. Weight loss was affected by bag type

up to 15 days of storage; weight losses were less for fruits from horizontal bags. Nutrition system and bag type had little effect on other parameters whereas, cultivar exerted a significant effect on all of the examined parameters. Afrodit had the best postharvest performance; fruits of Efes, Rawa and Afrodit could be stored for 15, 18 and 21 days, respectively.
