Optimum conditions for rapid propagation with clones of Acacia implexa

Abstract: Acacia implexa is an excellent multipurpose tree species in South China, however seed propagation will cause segregation of inheritable characteristics and then, limit its utilization. This study looked at the use of tissue culture to clone trees with three plant growth regulators (6-BA; NAA, ZT) in different levels, and appropriate methods for possible ways to prevent vitrification of adventitious buds by orthogonal experiment L9(34). Results of experiments on micropropagation of young stem sections for selected adult trees of A. implexa showed that a suitable medium for adventitious bud differentiation of the stem sections with axillary buds was:MS (Murashige and Skoog's medium)+1.0 mg·L-1 BA(6-benzyladenine) +0.2 mg·L-1 NAA(α-naphthalene acetic acid)+1.0 mg·L-1 ZT(zeatin), a suitable medium for adventitious bud multiplication was:1/2 MS(NH+4:NO-3=1:2)+1.0 mg·L-16-BA+0.05 mg·L-1 NAA, and a suitable medium for improving roots was:1/2 MS+0.1 mg·L-1 NAA. After transplanting, over 70% of the tube plantlets survived.
