Advances in horticulture plant biotechnologies provide new opportunities for researchers to study the field of vegetative propagation and genetic engineering. Developments of clonal propagation methods, especially somatic embryogenesis (SE), have numerous potential applications. This paper reviewed progress of research on SE in horticultural plants in last decade; analyzed plant regeneration having both direct and indirect SE from the characteristics of occurrence means, but mainly in an indirect way; and discussed the impact factors of SE, as well as reviewed the research in the practical applications of horticulture plants SE in the practice.
