Abstract: Effects of La3+ on the callus formation and growth , bud initiation and multiplication of Gerbera jasmesonil‘sunbird’were studied. Floral receptacle , leaf and bud explants were inoculated on the media with different concentration of La3+. The result showed that La3+ could stimulate the callus formation and growth , and the bud differentiation at low concentration , the suitable concentration was 10 mg/L in receptacle explants and over this concentration , the bud initiation was inhibited and much more explants turned browning. In leaf explants , the suitable concentration for callus formation and growth was 15 mg/L , and 30 mg/L for bud initiation and multiplication respectively.

Key words: Rare-earth element, La3+, Gerbera jamesonil, Tissue culture
