用分光光度计对抗寒力不同的苹果品种测定枝条花色素含量试验表明,苹果抗寒力与枝条皮层花色素的含量呈正相关。冬季苹果一年生枝条皮层中花色素的积累强烈。在秋冬时期,苹果枝条皮层花色素的含量可增加1～4倍,抗寒品种花色素的积累不但比非抗寒品种的要快,而且花色素的含量也最高。研究不同苹果品种对春季温度的反应表明,在
Using the spectrophotometer to test the anthocyanidin content of branches of apple cultivars with different cold resistance, the results showed that there was a positive correlation between the cold resistance of apple and the content of anthocyanin in shoot cortex. The accumulation of anthocyanidins in annual apple cortex in winter is intense. During autumn and winter, the content of anthocyanidins in apple branches cortex increased 1 ~ 4 times. The accumulation of anthocyanidins in cold-resistant varieties was faster than that of non-cold varieties, and the content of anthocyanidins was the highest. The response of different apple varieties to the temperature in spring showed that at
