Effects of Aminoethoxy Vinyl Glycine (Avg) on Fruit Quality and Bioactive Content of Jujube Fruit (Ziziphus Jujuba) Harvested at Three Maturity Stages During Cold Storage
In the study, the effects of aminoethoxy vinyl glycine (AVG), sprayed to jujube ( Ziziphus jujuba Mill. cv. 'Li') trees 2 weeks before the estimated harvest, and maturity stage on fruit quality characteristics and bioactive compounds during cold storage were investigated. Jujube fruit was maintained at cold storage for 45 days at 0±0.5 °C and 90±5% relative humidity conditions, and measurements and analyzes were carried out at 15-day intervals. During cold storage, the effect of AVG on retarding weight loss and softening of fruit flesh firmness was evident. At the end of the cold storage, the weight loss of T2 and T6 treatments was the lowest. The lowest respiration rate was measured in the T5 treatment. However, the highest fruit firmness was obtained by T2 and T4 treatments. In the T6 treatment, higher chroma and, on the contrary, lower L* and hue angle was measured compared to the other treatments. In T2 treatment, the highest vitamin C and the lowest soluble solids content were obtained. The highest total phenolics T3, T4 and T5; highest total flavonoids T4; The highest antioxidant activity (DPPH assay) was determined in T1, T3 and T5 treatments.As a result, it was revealed that AVG and maturity stage significantly affect fruit quality during cold storage of jujube fruit, and AVG can be used as a tool to maintain quality
