Abstract:
Winter pruning is an important practice in vineyard management.In present study，the germination rates，bearing branch rates，fruit bearing coefficients and berry quality of the main wine grape varieties growing in Guanzhong region of Shaanxi Province were investigated in different winter pruning modes.The results showed that the germination rates，bearing branch rates and fruit bearing coefficients were all higher with short cane (spur) pruning than other pruning modes.Meanwhile，short cane (spur) pruning enhanced the content of total reducing sugar in berries of ‘Cabernet Gernischt’，‘Carignane’，‘Yan 73’，‘Petit Manseng’，‘Muscat Blanc’ and ‘Italian Riesling’ and titrable acid in berries of ‘Cabernet Sauvignon’，‘Cabernet Gernischt’，‘Carignane’，‘Marselen’，‘Petit Manseng’，‘Muscat Blanc’ and ‘Italian Riesling’.Moreover，the berry skins of all the red wine grape varieties with the mode of short cane pruning，except ‘Cabernet Sauvignon’，had the highest content of total phenolics.Hence，short canes pruning was suitable for improving fruit bearing strength and berry quality of most wine grape varieties growing in Guanzhong region of Shaanxi Province.
