在冬季休眠期间对苹果枝进行热处理,发现需冷度不同的品种反应很不一致,有的萌芽受促进,有的受抑制;顶芽和侧芽的反应也不同。认为Chandler关于热处理能取代需冷性的论断过于简单。 During the winter dormancy, the branches of apple were heat-treated, and it was found that the varieties with different degrees of cold responded very inconsistently. Some of the germination was promoted and some of them were inhibited. The responses of the apical and lateral buds were also different. Think Chandler’s argument that heat treatment can replace chilling is too simple.
