The Effect of Different Concentrations of Plant Growth Regulators on Micropropagation of Kalanchoe blossfeldiana cv. White

Shoot tips from actively growing, greenhouse maintained plants ofkalanchoe blossfeldiana were cultured in vitro for shoot proliferation and rootinitiation on murashige and skoog (ms) basal medium supplemented withnaa and ba, both in concentrations of 0.00, 0.50, 1.00 and 2.00 mg l-1.results showed that the maximum plantlets height (7.012 cm), node number(4.516), root number (8.860) and root length (10.160 cm) were obtained inms medium containing 1 mg l-1 ba + 1 mg l-1 naa. maximum shootnumber (5.886), leaf number (8.980) and proliferation index (1.791) werecalculated in medium supplemented with 1 mg l-1 ba + 0.5 mg l-1 naa.minimum plantlets height (1.988 cm), node number (1.283), root number(2.720), root length (3.016 cm), shoot number (1.221), leaf number (2.015)and proliferation index (0.405) were obtained in medium without ba andnaa (control). fresh and dry weights of plantlets were calculated, too.about 85% of the micropropagated plantlets were established successfullyin acclimatization medium containing peat, perlite and sand (1:1:1).regenerated plantlets were morphologically identical with mother plants.
