ABSTRACT
<p><b>OBJECTIVE</b>To construct the fast propagation system of Houttuynia cordata Thunb. new line by selecting the proper type and concentration of plant growth regulators and proper explants.</p><p><b>METHOD</b>The different explants of Houttuynia cordata new line were cultured on MS media with different concentration of different plant grow regulators.</p><p><b>RESULT</b>Stem node over-ground and shoot tip were optimum explants for fast propagation. The stem which node grew on MS medium with KT at 0.5 mg x L(-1) could induce more leaves and grow higher. The shoot tip cultured on MS medium with 1.0 mg x L(-1) 6-BA could induce better callus. Adventitious shoots were better achieved from over-ground nodal explants cultured on MS medium supplemented with 6-BA at 1.0 mg x L(-1) and NAA at 0.2 mg x L(-1), or 6-BA at 0.5 mg x L(-1) and NAA at 0.2 mg x L(-1). MS medium with IAA at 0.2 mg x L(-1) was the best one on inducing roots.</p><p><b>CONCLUSION</b>The propagat coefficient can be highly improved by inducing adventitious shoots through stem node over-ground, and thus plentiful seeds for production can be provided.</p>
