Chilling and heat requirements and relationship between them for major grape cultivars under protected culture
摘要
Abstract
Chilling and heat requirements were studied in 22 grape cultivars under protected culture.Three different models ( ≤ 7.2 ℃ Model, 0～7.2 ℃ Model and Utah Model) for estimating chilling requirements and two different models (Growing Degree Hours Model and Effective Temperature Model) for estimating heat requirements were evaluated , and correlations between chilling requirements and heat requirements were established. Different chilling requirement and slight differences in heat requirements were observed in the studied cultivars. The cultivars examined showed a range of chilling requirements,between 573 h and 1 246 h( ≤7.2 ℃ Model)or between 573 h and 971 h(0～7.2 ℃ Model)or between 917 C·U and 1 090 C .U (Utah Model). The heat requirements ranged between 9 976 and 12 541 growing degree hours (GDH), or between 253 ℃ and 353 ℃ (Effective Temperature Model). The results indicate no correlation between chilling or heat requirement and ripening date , as well as a negative correlation between chilling requirements and heat requirements.关键词
