果树上应用激素,多偏重于外源调节。近年来,根据果树习性,利用栽培措施调节果树内源激素平衡,已开始引起重视。特别是根系培养在其中的作用,已有相当论述。由于根系具有合成一些重要激素的功能,因此,任何影响根系发育的因素均会对树体激素平衡产生影响。 Application of hormones on fruit trees, and more emphasis on exogenous regulation. In recent years, according to the fruit tree habit, the use of cultivation measures to regulate endogenous hormone balance in fruit trees, has begun to attract attention. In particular, the role of root culture in it has been quite discussed. Because the root system has the function of synthesizing some important hormones, any factors that affect the development of the root system will affect the hormone balance of the tree.
