ABSTRACT

<p><b>OBJECTIVE</b>To speed up seedling production of pasqueflower (Puzlsatilla chinenses) and their modernization in pasqueflower.</p><p><b>METHOD</b>With tissue culture method, primary culture of different explants, culture of cluster buds and their rooting culture were conducted on medium of treatment combinations of adding different hormones.</p><p><b>RESULT</b>The appropriate medium for different culture stages were MS + 6-BA 1.0-3.0 mg x L(-1) + NAA 0-0.05 mg x L(-1) + Sucrose 30 g x L(-1) in primary culture, MS + 6-BA 0.2 mg x L(-1) + NAA 0.02 mg x L(-1) + BR 0.00001 mg x L(-1) + Sucrose 30 g x L(-1) in differentiation and subculture of cluster buds, 1/2 MS + NAA 0.4 mg x L(-1) + Sucrose 20 g x L(-1) in rooting.</p><p><b>CONCLUSION</b>Applying stem tip and flower buds as explants, high frequency propagation of seedlings can be achieved with plant tissue culture in Pasqueflower.</p>
