Determination of Cold Damage and Lipid Peroxidation Levels of Karaerik (Vitis vinifera L.) Grape Cultivar Having Different Trunk Height in Winter Buds
Abstract :
This experiment was carried out to determine the cold injury of winter buds according to different trunk heights in Karaerik cv. grape cultivar grown in Erzincan province during the winter colds that occurred in 2012/13. In addition, the level of lipid peroxidation activity was examined in winter buds exposed to low temperatures. For this purpose, 1 year old shoots were taken in the spring before pruning and of the first 4 buds of one-year old shoot were examined with a binocular microscope after opening with a razor blade and low temperature damage was detected in the dormant buds. Lipid peroxidation level in winter buds was determined by malonindialdehyde (MDA) analysis. Falling winter temperatures up to -19.2oC the damage was caused 75cm, 100cm and 125cm trunk height shoots in winter buds average 24.10%, 30.2% and 22.9% respectively in this period. However, no significant difference was found between trunk heights according to the results of injury rate and lipid peroxidation activity level in winter buds. Along with that, 125cm trunk height the winter buds have been slightly more tolerant to low winter temperatures compared to other trunk heights. We are of the conviction may be a more accurate approach of investigation of the effects of trunk heights on yield and quality criteria for recommend which trunk height is more suitable for local vineyard in future work.
