Abstract
One of micropropagation methods was investigated by using a multiple-shoots protocol. Multiple shoot formation was obtained from excised axillary buds of Hypericum erectum on half-strength or basal MS medium supplemented with TDZ or BA. The optimal combination of shoot multiplication for the production of more shoots with a suitable size was MS medium supplemented with $0.005\;mg{\cdot}L^{-1}$ TDZ (6.5 adventitious shoots per node). In vitro rooting was carried on half-strength MS medium with $1\;mg{\cdot}L^{-1}\;GA_3\;and\;0.5\;mg{\cdot}L^{-1}$ IBA treatment. In addition, the rooted cuttings were showed a better root growth in the greenhouse and survived in more than 90%. The results show that the species can be micropropagated effectively by the application of axillary bud culture systems.
