Preliminary Results on Some Constitutional Changes in 1-MCP Treated Quince (Cydonia oblonga Mill.) Fruit during Cold Storage Period

This research summarizes effects of 1-methylcyclopropane (1-MCP) treatments on some compositional parameters in 'Esme' and 'Ekmek' quinces. Following harvest at the beginning of October, fruit were treated with 300 nl L-1 and 1000 nl L-1 1-MCP, respectively, at 12 degrees C for 20h and then stored at 0 +/- 1 degrees C and 85-90% relative humidity for six months. During storage, contents of sugars, organic acids, phenols and vitamin C were determined in fruit sampled at monthly intervals and quantified based on external standards.
