The effect of genotype on gerbera shoot multiplication in vitro

The multiplication rate of eleven gerbera cultivars was tested on a MS medium that contained 4.5% sucrose, 80 mg/l adenine sulphate, 100 mg/l L-tyrosine, 0.5 mg/l IAA and 2.0 mg/l N6-benzyladenine (BA). The highest multiplication rate (8 shoots) per inoculum in a 4 week period were shown by cvs. Ansofie, Terracerise and Lablinel ; cvs. Maria, Shanghai and Fresultane had a moderate rates (6-7 shoots), and cvs. Croduro, Raisa, Fredigor, Terramaxima and Fredibel had the lowest rates (4-5 shoots). Plantlets rooted effectively in three weeks on MS salts with 3% sucrose and 2.0 mg/l IAA, and successfully acclimatized to the greenhouse conditions.
