主 题：Blueberry Cultivars Overwintering Ability Annual Branch
摘 要：In order to select severe overwintering abilitied blueberry cultivars for cold resistance of annual branches, promoting breeding high quality cultivars, a study had been conducted into field-planting shoots overwintering ability and the relative conductivity, MDA content, SOD of 7 different kinds of blueberries under artificial cooling process. According to survey results, under field conditions, Different cultivars of blueberries showed significantly difference, ranging from 56.67% of Bluegold to 12.80% of Darrow. With the temperature decreasing, changes of relative conductivity, MDA content and SOD in annual branches had a strong regularity and the hardiness of these cultivars is: Northland Chippewa Coville Bluecroup Darrow Bluegold Powderblue.
