Abstract

The typical great scarcity and low availability and quality of water in the Spanish Mediterranean agrosystems, mainly in the southeast, have led to the performance of deficit irrigation strategies (DI). In this work, the effect of DI on the quality parameters at harvest and after chilling storage and commercialization of Chinese jujube (Ziziphus jujuba) fruits was studied. The irrigation treatments were: Control (T0), trees watered at 112.34 % of crop evapotranspiration (ETc), Half Irrigation (T1), trees irrigated at 64.19 % of ETc, and Without Irrigation (T2) where no irrigation was applied during the fruit development stage. Harvested fruits at commercial stage were stored for 37 days at 5ºC and 90% RH, followed by a simulated retail sale period of 5 days at 15ºC. Throughout storage and shelf-life the total soluble solids (TSS), pH, titratable acidity (TA), colour, caliber, weight loss and decay were monitored. As expected, T2 fruits showed the lowest caliber at harvest. After cold storage T2 fruits showed the highest TSS levels. After both cold storage and shelf-life periods, no differences in TA, pH and colour among irrigation treatments were found. As main conclusion, T1 fruits showed better quality at harvest and after cold storage and retail sale periods than that of T0, while saving 912.1 m3 ha-1 of water.
