摘要
利用0～7.2℃模型、≤7.2℃模型和犹它模型3种需冷量估算模型对设施葡萄常用品种的需冷量进行估算。结果表明,设施葡萄常用品种的需冷量值分布较广,若以0～7.2℃模型进行估算则介于573～971h之间,若以≤7.2℃模型进行估算则介于573～1246h之间,若以犹它模型进行估算则介于917～1090C?U之间;欧美种品种群品种需冷量值普遍高于欧亚种品种群品种;设施葡萄品种的需冷量值和其果实成熟期没有必然联系;3种需冷量估算模型估算设施葡萄品种的需冷量值差别较大。
The chilling requirements of 22 protected cultural grape cultivars were evaluated using three different models （≤ 7.2 ℃ Model. 0-7.2℃ Model and Utah Model） in 2 successive years. The cultivars examined showed a range of chilling requirements, from 573h to 1246h （≤7.2℃ Model） or from 573h to 971h （0-7.2℃ Model） , or from 917 CoU to 1090C·U （Utah Model）. The chilling requirements of the cultivars of V. vinifera x V. Labrusca were higher than that of the cultivars of V. vinifera. The results also indicated no direct correlation between chilling requirement and berry ripe time. The values of chilling requirement of grapevine cultivars estimated by three different models were different significantly.
