[Effect of medium components on callus induction and contents of polysaccharides in calli from Achyranthes bidentata].
OBJECTIVE
To study the effect of medium components on the callus induction and the contents of polysaccharides in calli from Achyranthes bidentata.


METHODS
Leaves and stems were selected as explants. The effects of six kinds of factors including basal culture medium, carbon source, 2,4-D, 6-BA, TDZ, CH on the callus induction and the contents of ABPS in calli on the high growth point were studied by orthogonal design method. The data were analyzed with range analysis and variance analysis.


RESULTS
To leaf, the optimal medium of callus induction was B5 with 2 mg x L(-1) 2,4-D, 0.5 mg x L(-1) 6-BA, 30 g x L(-1) glucose and 1 g x L(-1) CH; to stem, the optimal one was B5 with2 mg x L(-1) 2,4-D, 1 mg x L(-1) 6-BA, 30 g x L(-1) glucose and 0.5 g x L(-1) CH. In order to obtain higher contents ABPS, to leaf calli, the optimal medium was LS with 1 mg x L(-1) 6-BA, 1 mg x L(-1) TDZ and 30 g x L(-1) sucrose; to stem calli, the optimal one was LS with 1 mg L(-1) 2,4-D, 0.5 mg x L(-1) 6-BA, 1 mg x L(-1) TDZ and 30 g x L(-1) glucose.


CONCLUSIONS
The optimal media of callus induction were established with stems and leaves of A. bidentata as explants and with a view to an industrial production of polysaccharides by tissue and cell culture.
