【摘要】 连续2 a用3种模型分别对需冷量观察结果比较表明,犹他模型计算的需冷量较能客观地反映供试材料在扬州地区的萌芽表现,且不同砧木对藤稔葡萄需冷量的满足有重要影响。藤稔葡萄嫁接到高需冷量的砧木上其需冷量增高,嫁接到低需冷量的砧木上其需冷量降低。更多还原

【Abstract】 Comparing the applicability of three models measuring the chilling requirements with data of investigations in 2004 and 2005,it is found that the Utah model is much more suitable to describe the changes of dormant course of the grape buds in Yangzhou and different rootstocks play an important role in fulfilling the chilling requirements of dormant buds in Fujiminori grape.The chilling requirement of Fujiminori grape was increased when grafted on the rootstock which chilling requirement was high,or it was decreased.更多还原
