作者从生理生化的角度出发,扼要地叙述了核桃嫁接不易成活的原因;并证明核桃嫁接时单宁氧化、伤流和嫁接材料的发育年龄等因子对核桃嫁接成活率有深刻的影响。在个别因子的研究中,作者特别对嫁接时以单宁为中心的生化转化机制进行了探讨,这些不仅有助于了解核桃嫁接成活时内部生化转化的图景;同时对制订具体的嫁接方法,亦有着参考意义。
From physiological and biochemical point of view, the author briefly describes the reason why grafting of walnuts is not easy to survive; and it also proves that tannin oxidation, injury flow and the age of development of grafted materials have a profound impact on the grafting survival rate of walnut. In the study of individual factors, the author especially discussed the mechanism of biochemical transformation of tannin at the grafting stage, which not only helps to understand the internal biochemical transformation of the walnut grafted alive; at the same time, the specific grafting methods Has a reference value.
