Antioxidant Potential and Storage Stability of Sweet Cherries (Prunus Avium L.) Depending on the Use of 1- Methylcyclopropene

Plant growth regulator 1-methylcyclopropene (1-MCP) delays the ripening of many climacteric fruits and vegetables. However, the effect of 1-MCP has been studied to a lesser extent on non-climacteric fruit, showing variable results in delaying their ripening. In the present experiment the effects of using different doses: 1, 2, 4 uL of 1-MCP per liter in the form of Vidre + stickers (Fresh Inset) compared to control (without 1-MCP) on the quality parameters and shelf life of cv. Kordia and Regina was evaluated. One Liter clamshells of freshly picked sweet cherries were placed into a plastic bag for 24 hours. After that, all clamshells were placed into a storage chamber (2–3°C, 90–95% relative air humidity). The best results in terms of weight loss, stem browning, firmness and fruit quality after storage was obtained with samples treated with 1-MCP. Similar relationships were obtained with regard to the concentration of Vitamin C, total polyphenols, anthocyanins and the antioxidant activity FRAP.
