摘要
嫁接是农业生产中重要的栽培措施之一。砧木与接穗在嫁接后形成一个共生体,彼此间形成竞争与共生关系,这种关系的结果如何,与二者的亲合力有关。砧穗嫁接亲合力的大小主要取决于砧木与接穗双方生理作用的相似程度,不仅与接合所产生的影响有关,还与愈合后砧穗在生理上的相互适应有关,涉及嫁接亲合性与非亲合性机制、嫁接愈合的组织学和细胞学变化以及生理生化作用等多方面的问题。影响嫁接不亲合的因素很多,如砧穗内部组织结构的差异、生理生化的差异、病毒及病害、砧穗生长期长短、环境因素、激素水平等。
Grafting is one of the import methods in agriculture. A commensal body of rootstock and scion is produced after grafted, which forms commensal and competitive relationship between them. How the consequence develops is related to the affinity of them. It is significant to study the affinity between rootstock and scion in agriculture. The degree of affinity is determined by the analogical degrees of the physiological interaction between rootstock and scion, and is related to the physiological adaptability of them after concrescence. It involves in many aspects such as the mechanism of affinity and non-affinity of grafts, the histology and cytology of concrescence, and the physiological and biochemical interaction, etc. There are many factors affecting non-affinity, such as the differences in tissue and structure, physiological and biochemical characteristics, and growth period of rootstock and scion, and viruses, diseases, environment, and phytohormone, etc.
