Abstract:

The aim was to study the rapid propagation and differentiation of rhizomes of Cymbidium goeringii ‘Jiyuan’ and ‘Ruyisu’. Four factors including basic medium, 6-BA, NAA and IBA were designed to study the effects on rapid propagation and differentiation of rhizomes. The most appropriate cultivating medium was 1/2MS. 1/2MS+NAA 5.0 mg/L+6-BA 0.5 mg/L was the best propagation medium and the rhizomes differentiates in high rate on 1/2MS+NAA 0.5 mg/L +6-BA 2.0 mg/L. Propagation and differentiation in vitro culture were the important means and methods for speeding up the cultivation of new varieties.
