| 摘 要： | 以茉莉继代试管苗为试材,研究了不同生长素、生根方式、继代次数以及培养基支持物对茉莉生根过程的影响。结果表明:最佳生根培养方式为1/2 WPM+NAA 1.0 mg/L处理7 d后转入空白培养基进行两步法生根,生根率为98.41%;经1~4次继代的试管苗生根效果好于5或6次继代的试管苗;以蛭石为培养基支持物诱导生根效果最好,生根率达到100%,移栽成活率97.14%,根系活力、POD和SOD活性也均高于其他培养基支持物。

| Abstract: | 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... |
