Zhang et al. (2006) found that optimal induction medium for dormant buds of P. lactiflora was half-strength MS medium ( Murashige and Skoog, 1962) including 1 mg l−1 gibberellic acid (GA3) and 1 mg l−1 6-benzyladenine (BA); the most suitable medium for shoot multiplication was half-strength MS to which 1 mg l−1 BA and 0.5 mg l−1 kinetin (KT) were added, and the preferred root-induction medium (RIM) was half-strength MS plus 1 mg l−1 indole-3-butyric acid (IBA). In the latter study, the cultivar(s) used were not specified, diluting the impact and relevance of that study, altho
