The effects of different kinds of auxins,rooting inducement modes,subculture times and supporting substances of the medium on the rooting of isolated jasmine seedlings were studied.The results showed that two-step rooting mode,i.e.,pre-cultivating rootless shoots on the rooting medium containing 1/2 WPM and NAA 1.0 mg/L for 7 days(first step),followed by being transferring to blank medium containing only 1/2 WPM(second step),was the optimal rooting inducement method,it could obtain a rooting rate as high as 98.41%.Rooting ability of the test-tube shoots subcultured for 1~4 times was better than that subcultured for 5~ 6 times.Moreover,vermiculite was the best supporting substance of the medium for rooting inducement.100% rooting rate and 97.14% survival rate of transplanting were obtained on vermiculite,the root vigor,activities of POD and SOD in roots on vermiculite were higher than those on other supporting substances.
