Effect of Combined Solution (Ascorbic Acid, Salicylic Acid and Methyl Jasmonate) Application on Blueberry (Vacciniumcorymbosum L) Fruits Cold Storage
Blueberry fruits were harvested in the middle summer in western part of Georgia. After harvesting average
samples of fruits were treated with combined water solution (CS) of ascorbic acid (0.5%), salicylic acid (0.03%) and methyl
jasmonate (0.002%). Data showed that treatment with CS caused significant retention of polyphenols degradation process
during storage period. Antioxidant activity of fresh fruits was equal to 689.22±34.46 mg equivalents of vitamin-C per 100 g
of fruits. During storage this value decreased to423.15±21.15 and 589.62±29.48 mg equivalents of vitamin-C per 100 g of
fruits for control and treated samples respectively. After 7 days storage period TSS of fruits decreased from 12.47±0.62 % to
10.25±0.51 % in control samples and to 12.00±0.6 % in treated samples probably because of respiration process. Difference
between the treated and untreated samples was statistically significant (p<0.05).
