Abstract:

The experiment was studied on the statistics of germination rate and growth coefficient and the determination of soluble sugar, proline content and superoxide dismutase (SOD) activity of different wine grapes overwintering after under arid condition, the results showed that the germination rate from high to low was SO4>520A>Ln33> Vitis amurensis×Vitis riparia >5BB> Beta >101-14>110-R > Cabernet Franc >LDP294= fenghuang = Pinot Noir > Merlot184> Vidal > Merlot 347 under arid condition. The content sequence between soluble sugar and proline showing the same basically, which was in accord with the germination rate. In contrary, the SOD activity had significantly differences with soluble sugar and proline. This study suggests that the stress resistance of wine grape varieties could be selected effectively through the statistics of germination rate, growth status and determination of the soluble sugar, proline content.
