Effect of postharvest spermidine treatments on quality and biochemical properties of nectarine fruits

In this study, the effect of spermidine (SP) treatments at different doses after harvest on changes in pomological and biochemical contents nectarine fruits was determined. The were placed cold storage (4 ± 0.5 °C 90 5% RH) for 30 days. Specific organic acids phenolic compounds from analyzed by HPLC device. Weight loss decay values, which are quality criteria fruits, increased during compared to period. 1.0 mM SP application found be more successful preservation visual (fruit pulp firmness weight loss) properties storage. At end period (30th day), determined as 3.27% control group 1.84% 1.5 treatment. Fruit flesh value, is one important parameters affecting life 30.97 N 37.06 doze day). Contrary acidity total soluble solids content (TSS) fruit juice pH values research, when acid compound examined; it that dominant malic chlorogenic acid, respectively. ratio 4.89 g/kg 6.66 treatment 30-day Chlorogenic recorded 6.86 mg/100g 8.82 a dose effective protected
