目的提高盾葉薯蕷藥材的品質(zhì)。方法通過(guò)組織培養(yǎng)，對(duì)誘導(dǎo)獲得的盾葉薯蕷四倍體株系，進(jìn)行了試管苗抗氧化酶活性及薯蕷皂苷元含量分析。結(jié)果大部分四倍體株系A(chǔ)PX活性、SOD和POD比活力高于或相近于二倍體株系。經(jīng)誘導(dǎo)獲得的四倍體株系試管苗與對(duì)照相比薯蕷皂苷元含量有較大差異，大部分四倍體株系薯蕷皂苷元含量都超過(guò)了二倍體株系。結(jié)論經(jīng)誘導(dǎo)獲得的四倍體株系在抗氧化酶活性及有效成分含量方面與二倍體表現(xiàn)出明顯差異，說(shuō)明多倍體誘導(dǎo)可以作為盾葉薯蕷優(yōu)良品種選育的途徑。

　　Abstract：ObjectiveTo improve the yield and quality of D.  zingibiernsis C.H.Wright . MethodsThe research project of polyploidy breeding by tissue culture was done. The antioxidant enzyme activities and the diosgenin were analyzed in polyploidy lines. Results The results showed that SOD and POD activities in most of autotetraploid lines were not lower than those of diploid line, furthermore，the content of diosgenin in most induced plantlets was higher than that in control. Conclusion There was difference between  autotetraploid and control lines in diosgenin content and antioxidant enzyme activities，therefore，inducing autotetraploid can be effective way to breeding the superior varieties.
