Abstract: Research on rooting mechanism of apple cutting is reviewed from morphological anatomy of adventitious root formation of cutting, physio-biochemical basis of cutting rooting and molecular biology of cutting rooting. At present, morphological anatomy structure of adventitious root formation in apple has been known that apple dwarf stock belongs to induced root primitive type, not hidden root primitive type. Hormones, enzymes, nutrients, water, and other physio-biochemical substances affecting rooting have been studied, it is thought that cutting rooting is affected by many factors, the formation of root primordium is the result of the dynamic equilibrium by the factors, and the reason of adventitious root formation in cutting is revealed preliminarily from molecular level. Relevant research results are of significance to regulate the formation and development of adventitious root, and it is necessary to carry out deep and comprehensive research on the formation mechanism of adventitious root from molecular level in the future.
