Quality and Shelf Life of Torkaman Grape Cultivars and Local Cultivars

The table grape (Vitis viniferal) is a non-climacteric fruit with a relatively low rate of physiological activity and is subject to serious water loss after harvest that can result in dry brown stems, shattered grapes, and wilted and shriveled grapes. Grapes can be stored for a short time, but increasing living standards have increased the demand for fresh grapes in Iran. The possible introduction of new grape varieties of good quality with long shelf lives has been a focus of attention. The present study compared the performance of 8 Torkaman cultivars and 3 local cultivars (Koladary, Kajangor, Rezghy). The result showed that the Torkaman cultivars had good quality and quantity characteristics and, most importantly, longer shelf lives and are recommended as potential varieties for cultivation.
