【摘要】 本研究以10个葡萄种类和品种为试验材料,研究了葡萄抗寒力和伤流液中还原糖含量、氨基酸含量与种类间的关系。抗寒力强的葡萄种类的还原糖含量远远低于抗寒力弱的栽培品种。苏氨酸含量在伤流液中显著高于其它氨基酸,随着气温升高,生长加速,苏氨酸含量进一步增高。抗寒力强的比抗寒力差的增加的多。抗寒力强的葡萄种类的伤流液中丝氨酸含量一般都低于抗寒力差的栽培品种,随着气温升高和生长加速,丝氨酸消失,而甘氨酸却出现在伤流液中更多还原

【Abstract】 Ten species and cultivated varieties of grape were used as experimental material in the study。The content of reduced carbohydrates, the content and the kinds of amino acids in the exudate of grape in relation to the cold resistance were studied。The content of reduced carkohydrates in the stong cold resistant species of grape were very marbedly lower than the weak cold resistant cultivated varieties。The content of threonine in the exudate remarkably higher than other amino acids。The content of threonine was increased with the rising temperature and the promoting growth, the increas in the strong cold resistant species more than the weak cold resistant species。The content of serine in the exudate of the strong cold resistant species of grape were generaly lower than the weak cold resistant cultivated varieties, the serine was disappeared with the rising temperature and the promoting growth, arid the glycine was appered in the exudate。更多还原
