A Review of Research Progress in Acacia Tissue Culture

Acacia spp. is a fast-growing tree species, characterized by high production, good quality, well adapting and wide use, which plays an important role in forest production in southern China. Understanding and grasping tissue culture techniques of Acacia spp. are significant to promote their industrialized development. This paper reviewed the research progress in tissue culture techniques for Acacia species since the 1980s with regard to explants, basic medium, culture conditions, plant growth regulators and regenerated plantlet transplant. Based on the analysis of existed problems of Acacia tissue culture, related solutions were proposed and future study on plant tissue culture was prospected, which would provide references for industrialized culture and breeding of Acacia species.
