木本植物的越冬性决定于长期形成的年形态——生理的周期性。年形态——生理的厨期性表现着它对某一地区气侯条件的适应程度。因此,在探讨测定木本植物越冬性的有效方法的时候,必须从关于木本植物的季节形态——生理周期性的现代概念出发。只有基于不同的种和品种的生物学特性的方法,才能对它的越冬性得出可靠的资料。 The winter of woody plants depends on the long-term formation of the form - the physiological cycle. The form of the year-physiology shows its adaptation to the climatic conditions in a particular area. Therefore, when discussing effective methods of determining the winteriness of woody plants, we must proceed from the modern concept of the seasonal form of woody plants - the physiological cycle. Only methods based on the biological characteristics of different species and varieties can produce reliable data on their overwintering nature.
