[Tissue culture and plant regeneration of Ardisia crenata].
OBJECTIVE
Our research studied the fast-breeding technology of Ardisia crenata sims by using tissue culture and provided the scientific foundation for industry production.


METHODS
The effects of axillary buds and plant regeneration of different basic medium, hormones and additives on induction and multiplication were studied.


RESULTS
The best culture medium for the induction of axillary buds, which took the stems of A. crenate were as explants, was MS + 6-BA 0.5 mg x L(-1) + NAA 0.1 mg x L(-1), and the best medium for multiplication was MS + 6-BA 2.0 mg x L(-1) + NAA 0.1 mg x L(-1) + KT 0.5 mg x L(-1), the best medium for roots generation was 1/2MS + IBA 0.2 mg x L(-1). We also found that the roots'generation, roots rate and mean number of roots can be promoted by adding 0.2% Ac, and the most suitable ground substance was river sand-perlite-vermiculite (1:1:1) or perlite-vermiculite (1:1). With axillary buds and plant regeneration methode, more than 80% A. crenata sims could be regenerated integratedly.


CONCLUSIONS
A. crenata sims can be regenerated integratedly and breeded fast by using axillary bud proliferation technology.
