In vitro propagation of Gerbera (Gerbera jamesonii Bolus)

Abstract

Gerbera plant Gerbera jamesonii is classified according to the flower colors to four strains: white, yellow, pink and purple. Capitulum and scape explants were tested on MS medium in half or full salts strength, supplemented with different combinations of plant growth regulators cytokinins kintin (Kin) and benzel adinine (BA), auxin indolacitic acid (IAA). Results revealed that the capitulum showed better response to shoot formation 64.13% whereas the scape did not show response. Yellow flowers showed higher response in shoot formation 37.5% than other strains. growth regulators combination BA and IAA (3.0 + 0.1) mg/L respectively showed better response for shoot multiplication. Auxin IBA (0.5) mg/ L gave better rooting percentage 60% than other auxins IAA and NAA all concentrations. The acclimatization of the gerbera was 78.59%.

Standardization of an in Vitro Regeneration Protocol in Gerbera (Gerbera jamesonii Bolus Ex. Hooker F.)

“…Cytokinin to auxin ratio is critical. It is clear from the above findings that cytokinin (BAP) is a potent plant growth regulator for generation of Shailaja (2002) who obtained highest multiplication rate in gerbera with 3.0mgL -1 BAP. Results presented in Table 2 show that average length of shoots decreased significantly with higher concentration of cytokinin (BAP) when in combination with NAA.…”

Effect of Salt Concentration on Three Cultivars of Gerbera jamesonii

“…The best initiation and proliferation of shoots were observed on MS medium with 1 mg/L BAP, 0.030 mg/L IBA, and 0.025 mg/L NAA, which showed almost identical results. In another study, [11] found that the capitulum responded better to shoot formation at 64.13%. In contrast, there was no response observed on the scale.…”
