采用高效液相色谱 ( HPL C)测定经 Na C1胁迫后马铃薯脱毒试管苗 Vc的含量。结果表明 ,盐胁迫的脱毒苗植株其内部 Vc含量 ( 4 .2 4 8mg/ 10 0 g鲜重 )是对照液体 MS培养基生长下 Vc含量 ( 1.368mg/ 10 0 g鲜重 )的 3.10倍。然而 ,未经处理的脱毒苗生物产量 ( 0 .2 2 1g/株 )是盐处理 ( 0 .12 51g/株 )的 1.767倍 ,这是盐胁迫的结果
High-performance liquid chromatography (HPL C) was used to determine the Vc content of potato virus-free seedlings after NaCl stress. The results showed that the Vc content (4.248mg / 100g fresh weight) of the virus-free seedling plants under salt stress was 3.10 times higher than the Vc content (1.368mg / 100g fresh weight) grown on the control liquid MS medium . However, the biological yield of untreated virus-free shoots (0.221 g / plant) was 1.767 times that of salt treatment (0.1251 g / plant), which is the result of salt stress
