近年来,桃树上矮化砧的利用和抗根结线虫砧木的育成使人们感到极大兴趣,问题是如何保持这种优良砧木性状的一致性。本文从抽象生根的解剖学和生理学的研究结果,阐明了桃树不定根形成过程中的解剖学变化及有关组织化学变化,阐明了桃树插条中碳水化合物、内源激素、生根辅助物质及外源激素对生根的作用,并指出有关插条制备和插条环境与生根的关系。最后认为桃树的枝插繁殖可望成为一种有效方法。 In recent years, the use of dwarfing anvil on peach trees and resistance to root-knot nematode stock raising people are greatly interested, the question is how to maintain the consistency of this good stock performance. Based on the anatomical and physiological findings of abstract rooting, the anatomical changes and histochemical changes during the adventitious root formation of peach trees were clarified. The effects of carbohydrate, endogenous hormones, rooting auxiliary substances, Effects of source hormones on rooting, and pointed out the relationship between cuttings preparation and cutting environment and rooting. Finally, the peach tree branch propagation is expected to be an effective method.
