Abstract: | Summary This study reports a method for high-frequency shoot organogenesis and plant establishment of Potentilla potaninii Wolf. Hypocotyl and cotyledon explants of P. potaninii were cultured on Murashige and Skoog (MS) medium supplemented with various concentrations of benzyladenine (BA) and α-naphthaleneacetic
acid (NAA) to induce adventitious shoot formation for micropropagation. The highest frequency of adventitious shoot regeneration
was achieved from hypocotyl and cotyledon explants grown on MS medium supplemented with 5.0 mgl−1 BA and 1.0 mgl−1 NAA. The regenerated shoots rooted most efficiently on half-strength MS medium supplemented with 1.0 mgl−1 NAA and 0.5 mgl−1 indole-3-acetic acid or indole-3-butyric acid. The acclimatized plants with normal morphology and growth characters flowered
and set seeds in the following year. |
