水分在苹果树组织中起重大的作用,它对于果树正常地通过生理过程以及形成对严寒、干旱、盐渍化及其他不良环境条件的抵抗性有极其重要的意义。 由于植物形态的改变,环境条件的影响,采用不同的管理方法,水分状况的变化是非常复杂的。而在多年生果树上(广泛应用的外科手术)──修 Moisture plays a major role in the organization of apple trees and is of crucial importance to the normal physiological processes of fruit trees and their resistance to severe cold, drought, salinization and other adverse environmental conditions. Due to changes in plant morphology, environmental conditions, the use of different management methods, changes in water status is very complicated. In perennial fruit trees (widely used surgical procedures) - repair
