ABSTRACT
Objective:
To optimize the proper condition for callus induction of Asarum heterotropoides var. mandshuricum.Methods:
The effects of different explants, medium types, and plant growth regulators on the callus induction of A. heterotropoides var. mandshuricum were studied by using the petioles and leaves as explants. Also we aimed to discover the morphology characteristics of callus in different periods through paraffin method.Results:
The efficient callus induction medium was 1/2 MS + 0.6 mg/L 6-BA + 0.15 mg/L NAA while using petioles and leaves during young period as explants. Callus induction from young leaves lasted so long time. Furthermore it was found that the induced calli were embryogenic for they were composed of compact, small and irregular arrangement cells. Subsequently these calli could be differentiated to develop the regeneration plantlet.Conclusion:
Young petiole is the optimal explant for callus induction of A. heterotropoides var. mandshuricum, and the efficient callus induction condition we optimized would provide a basis for establishing the subsequent regeneration system.
