In vitro micropropagation of a medicinal plant species Sophoraflavescens
BIOLOGIA PLANTARUM 47 (1): 117-120, 2003/4，-0001，（）：
A micro-propagating system based on the young stem node segments of Sophora flavescens Ait. (Fabaceae) was established. Murashige and Skoog (MS) basal medium supplemented with 8.88μM 6-benzyladenine (BA) plus 2.69μM a-naphthalene acetic acid (NAA) and that with only 5.37μM NAA were found the best in promoting proliferation of shoots and induction of root, respectively. Percentages of shoot induction and number of shoot per explant were up to 93.4% and 4.2 and rooting rate to 82.4%, respectively. The segments of the regenerated shoots could be continuously induced to reproduce new shoots through subculture on the same medium in 30-d intervals and still kept this activity after being subcultured for 6 generations. After the regenerated plantlets were transplanted to field, they grew well, showing no any visible abnormalities.
