| 摘 要： | 比较了以能量为100kev，剂量为10^15/cm^2碳离子注入的甜菊种子萌发过程的细胞学效应和过氧化物酶活性，发现萌发4d的甜菊幼苗核异常细胞率，染色体畸变频率，细胞核，叶绿体，线粒体的损伤皆明显高于对照组，而细胞发裂指数和POD活性显著低于对照组；萌发第10d，上述表征已与对照组呈不显著差异，表明低能碳离子注入甜菊所引起的损伤已基本修复。

| Abstract: | Through comparing the effects of carbon ion with energy of100kev and dosage of10 15 /cm 2 implatation on Stevia rebaudiana Bertoni germination about cell biological effects and POD activities,we found Stevia rebaudiana Bertoni of4days,whose abnormal cell nucleus,chromosomes,POD activities,the injures of cell nucleus,choroplasts and mitachondria are higher than the control group(CK),then whose division index of Stavia rebaudiana Bertoni seedling cell was lower than that of the control group.When it grew to10days the difference of the above indexes was nitable.It showed that injuries done by low energy carbon ion implatation on Stevia rebaudiana Bertoni has been repaired. |
