摘　　要：在冷冻胁迫条件下,测定了葡萄属12个种45个株系枝条的膜透性变化、含水量动态变化及萌芽能力3项指标,并以种内不同株系间3项指标的平均值综合评价了12个种的抗寒性。结果表明,我国葡萄属野生种(东亚种群)山葡萄、燕山葡萄以及美洲种群中的河岸葡萄为高抗类型;蘡薁葡萄、复叶葡萄、毛葡萄为中抗类型;秋葡萄、刺葡萄、瘤枝葡萄为低抗类型;秦岭葡萄、麦黄葡萄和欧洲葡萄为不抗类型。抗寒性指标间相关性分析表明,利用平均隶属度评价葡萄抗寒性最为科学,为鉴定葡萄新种质提供了依据。Under cold stress condition, cold hardiness of 12 Vitis species including 45 lines （cuhivars） was identified based on the leakage of electrolytes, water loss ratio and percentage of bud bursting on the stem and estimated the hardiness resistance of 12 V. species by the average of Subordinate Function （SF）. The results showed that V. amurensis, V. yeshanensis and V. riparia were the most resistant to the hardiness; V. adstricta, V. piazezkii and V. quinquangularis were middle resistant; V. romanetii, V. davidii and V. davidii var. cyartocarpa were less resistant; V. qinlingensis, V. bashanica and V. vinifera were susceptible to cold stress. Correlation analysis of hardiness indexes showed that it was scientific to use average of SF for evaluating grape hardiness, so it can be used to evaluate cold hardiness of new Vitis germplasm resources.
