Effect of Pre-Harvest Organic Cytokinin Application on the Post-Harvest Physiology of Pepper (Capsicum annuum L.)

Peppers are cultivated in almost all provinces Turkey, making up approximately 7% of the world’s production. In this study, effects pre-harvest cytokinin application on postharvest physiology pepper (Capsicum annuum L.) fruits (cv. Akra and Melek F1) grown ecological conditions Turkey (Van, eastern Turkey) were investigated. During growing period, organic cytokinin(nytrozine) at two concentrations (50 100 ppm doses) was applied by spraying. harvested green maturity then stored 12 °C for 28 days. Changes color, respiration rate, exogenous ethylene amount, antioxidative enzyme analysis (SOD, CAT APX), lipid peroxidation, total phenolic content (TP) antioxidant activity (AA) determined just after harvest 7th, 14th, 24th 28th L* values both varieties control sample had fluctuations during storage, they slightly decreased days, except end value cv. F1 with a 50 addition. terms rate values, difference between applications found to be statistically significant, 14th days F1; 0th F1, respectively. It observed that can delay aging peppers cultivars As result, as used has an origin, is not synthetic does have negative effect human health, it safely without significant loss quality characteristics peppers. These positive in-package gas composition, enzymes, phenolics activity.
