同工酶是近代研究植物起源、分类、遗传变异和杂种优势的一种生理方法.近年来已广泛应用于农作物、蔬菜和果树的遗传育种工作中.本研究试图探讨不同桃树品种;不同杂交组合后代;同一品种相同器官和同一器官不同部位以及同一器官不同发育时期的过氧化物酶同工酶的不同表现形式,即“酶谱差异性”.如果能把这种酶谱的差异 Isoenzyme is a physiological method to study the origin, classification, genetic variation and heterosis of plants in recent years and has been widely used in the genetic breeding of crops, vegetables and fruit trees in recent years.This study attempts to explore different peach varieties; Combination of offspring; the same species of the same species and the same organ at different parts of the same organs and different developmental stages of different forms of peroxidase isoenzyme different forms of “zymogram differences.” If this zymogram differences
