In this study the effect of cold injury on buds of 21 grape cultivars was investigated in 2019 and 2020 by exposing of one-year-old cuttings to sub-zero temperatures. Based on the results, there was a significant difference among cultivars for (flower) bud viability. The cold resistance of 11 selected grape cultivars was examined under the temperatures of +4, 0, -2 and -4 °C in a factorial randomized complete block design. The highest level of free proline was measured in Amin while Torkamanestan 4 had the lowest amount. The highest level of catalas belonged to black Muscat and Aligone. Black muscat and Aligone cultivars had the highest level of guaiacol peroxidase and ascorbic acid, respectively. In contrast, the cultivars of Khalili Dirras and Torkamanestan 4 had the lowest level of catalase and ascorbate peroxidase, respectively. Finally, Torkamanestan 4 had a lower score and was identified to be a cold sensitive cultivar.
