Preliminary study on Anemarrhena asphodeloides tissue culture / 中草药

ABSTRACT

Objective: The tissue culture of Anemarrhena asphodeloides was preliminarily studied to establish A. asphodeloides regeneration system. Methods: The establishment of A. asphodeloieds sterile system, tiller bud proliferation, tiller callus induction and its re-differentiation as well as transplanting of regenerated plantlets were studied by plant tissue culture and single factor test method. Results: The best disinfection way of A. asphodeloides seeds was firstly dealt with 75% ethanol for 30 s and then dealt with 0. 1% HgCl2 for 15 min; The best medium of bud proliferation for A. asphodeloides tillers was MS+KT 1 mg/L+NAA 0.5 mg/L; The best medium of A. asphodeloides tiller callus induction was MS+KT 2 mg/L+NAA 0.5 mg/L; The best medium of A. asphodeloides tillers callus redifferentiation was MS+ KT 2 mg/L+NAA 0.1 mg/L; The best rooting medium of A. asphodeloides callus regeneration buds was 1/2 MS+NAA 0.5 mg/L; The best transplanting substrate of A. asphodeloides plantlets was humus soil. Conclusion: The regeneration system of A. asphodeloides is established, which provides a technological basis for factory production of A. asphodeloides plantlets.
