根据苹果抗寒力强弱与一年生枝条皮部花青素的含量呈正相关的关系，采用色价法测定不同苹果品种枝条皮部花青素的含量，鉴定出不同品种苹果的抗寒力。结果表明：大秋、黄太平、金红、Ｋ９ 和２７７ 五个栽培品种抗寒力大小的顺序为：大秋＞ 黄太平＞ 金红＞ Ｋ９ ＞ ２７７ 。 According to the positive correlation between the degree of cold hardiness and anthocyanin content in annual branches, the content of anthocyanin in branches of different apple varieties was determined by the color value method, and the cold resistance of different apple varieties was identified. The results showed that the order of cold tolerance of the five cultivars: Dayu, Huangtaiping, Jinhong, K9 and 277 were as follows: Dayu> Huang Taiping> Jinhong> K9> 277.
