Abstract:The influences of different combinations of plant regulators, sucrose concentration and culture modes on proliferation rates and the quality of auxiliary buds were studied in Anthurium andraeanum cv. Sonate in liquid culture. Differences in the proliferation were compared among A. andraeanum cvs. Sonate, Valentino and Julanba. Nitsch basal medium supplemented with 0.5 mg L-1 BA, 1.0 mg L-1 KT and 30 g L-1 sucrose was suitable for auxiliary bud proliferation of Sonate under liquid flask-shaking culture condition. Auxiliary bud proliferation of Sonate was promoted by the light of 20 μmol m-2s-1 of 25-day culture followed by 40 μmol m-2s-1, with the bud proliferation rate of 11.1 and the average bud length of 1.4 cm. The cultivars, Sonate, Valentino and Julanba, were well propagated under the above culture condition, especially Sonate and Valentino, but they showed differences in auxiliary bud emergence.
