远缘嫁接在果树和蔬菜方面应用比较广泛,在农作物上的应用还比较少见。红薯与蕹菜、红薯与牵牛花、红薯与天茄儿和月光花等的嫁接,过去曾有报导,特别是与月光花的远缘嫁接成功较多。但是,都是以红薯为接穗的。而以红薯为砧木,以绿豆为接穗的试验,则是没有先例的。河南省商丘地区农林科学研究所孟昭璜同志首先进行了这一试验,并获得了成功是值得祝贺的。对红薯与绿豆远缘嫁接所引起后代变异的深刻程度,我们进行了多方面的研究,现将细胞学 Distant grafting in fruit trees and vegetables is widely used in crop applications is still relatively rare. Sweet potatoes and water spinach, sweet potatoes and morning glory, sweet potatoes and children and moonlight flower grafting, in the past have been reported, especially with the distant success of the moonlight grafting more successful. However, sweet potatoes are scion. The sweet potato as the rootstock, mung bean scion test, there is no precedent. Comrade Meng Zhaoguan, Shangqiu Academy of Agriculture and Forestry Sciences, Henan Province, conducted this experiment first, and it is worth congratulating on his success. On the sweet potato and mung bean far-grafted offspring caused by the degree of variation in the offspring, we conducted a wide range of research, cytology
