Effect of Ascorbic Acid, Salicylic Acid and Methyl Jasmonate Combined Application on Cherry(Prunus Avium L.) Fruits Cold Storage

Cherry fruits were harvested in the middle summer in eastern part of Georgia. After harvesting average samples of fruits were treated with combined water solution (CS) of ascorbic acid (1%), salicylic acid (0.5%) and methyl jasmonate (0.005%). Data showed that treatment with CS caused significant retention of polyphenols degradation process during storage period. Four main anthocyanins were identified in cherry fruits: Cyanidin-3-O-glucoside, Cyanidin-3-O-rutinoside, Peonidin-3-O-rutinoside and Peonidin-3-O-glucoside. Anthocyanins amount in fresh fruits was33.48±1.67mg100g-1.After 21 days storage their content degraded down to 8.19±0.41 mg100g-1and 12.07±0.65 mg100g-1in the control and treated samples respectively. Antioxidant activity of fresh cherry fruits was equal to 188.96 ± 9.49 mg equivalents of vitamin-C per 100 g of fruits. During storage this value decreased to 92.47±4.62 and 151.35±7.56 for control and treated samples respectively. After 7 days storage period TSS of fruits decreased from 14.25% to 12.56% in control samples and to 13.24% in treated samples probably because of respiration process. But difference between the treated and untreated samples was not statistically significant. Keywords - Cold storage; Antioxidant activity; methyl jasmonate.
