Abstract
In this experiment the stem segments with nodes of the gerbera(Gerbera jamesonii Bolus) sterile seedlings were used as explants to study the effects of different hormone combinations and concentrations on the induction,proliferation and rooting of G.jamesonii shoots.The obtained results showed that the adventitious buds were directly induced from the gerbera stem segments with the node in 0.8-1.2 cm,without through the way of callus.The best induction medium for gerbera stem segments with the node was the MS medium with BA 3.0 mg·L-1 and NAA 0.1 mg·L-1.Higher concentrations of 6-BA were conducive to the improvement of the proliferation coefficient,but vitrification phenomenon was prone to occur.High concentrations of NAA would make the leaves chlorotic,so the most suitable medium for the proliferation was MS medium with BA 2.0 mg·L-1 and NAA 0.3 mg·L-1.Gerbera bud-seedlings rooting had a wide concentration range.The best rooting medium was 1/2MS medium adding NAA 0.2 mg·L-1.
