| Abstract: | The adventitious roots induced by IAA or IBA from the base of in vitro shoots of Sophora japonica L. are long and slender. They develop from the surface of stem directly, and the rootsystem is well developed. NAA induce the callus formation from the base of in vitro shoot first, then the adventitious roots differentiate from the callus. The roots are short and thick. Although the NAA is the most efficient exogenous growth regulator for rooting, the roots grow very slowly and the surfaces of them are often calliferous. 2,4 D could induce the base of in vitro shoots forming numerous callus, but inhibit shoots forming root. |
