Adventitious shoot regeneration from in vitro cultured leaves of London plane tree (Platanus acerifolia Willd.).

Adventitious shoots were successfully regenerated from leaf explants of in vitro cultures of Platanus acerifolia Willd. The leaves of three clones (genotypes), designated as PH1, PH2 and PC, respectively, were wounded by three to four transverse cuts through the midvein and cultured on 26 media based on Murashige and Skoog (MS) basal medium, containing different concentrations of 6-benzylaminopurine (BAP) in combination with different concentrations of indole-3-butyric acid (IBA). The highest regeneration rate (>90%) and the largest number of shoot clumps per regenerating leaf (>4 shoot clumps/explant) were obtained with leaves of genotype PH2 cultured on MS basal medium supplemented with 17.76 microM BAP and 4.92 microM IBA. The other two genotypes, PH1 and PC, showed very low capability of shoot regeneration (<10%) on all the media tested. Shoots on leaf explants originated mainly from callus that developed around the cut end of petioles and along the cuts across the midvein. The regenerated shoots were micropropagated, rooted and transplanted to the soil successfully.[1]
