| Abstract: | The stem-segements with axillary buds of Polygonum capitatum were cultured for its rapid propagation to produce its quality seedlings.The results showed that the germination rate of axillary buds cultured on MS medium was up to 93.3%,the optimum medium for bud multiplication was MS supplemented with 6-BA 4.0 mg/L and its multiplication time could reach 4.2,the optimum medium for inducing roots was 1/2MS NAA 0.2 mg/L and its rooting rate could reach 100% and the survival plantlet rate transplanted in a substrate with an equal volume of humus soil and vermiculite was 93.3%. |
