摘要
从茄红素含量、细胞总鲜重及茄红素总产量三方面 ,研究了培养基中 2 ,4-D浓度对胡萝卜悬浮培养细胞茄红素合成的影响。结果表明 ,2 ,4-D浓度在 0 .0～ 5 .0 mg/ L范围内 ,随着浓度升高单位鲜重细胞中茄红素含量增加 ,浓度为 5 .0 mg/ L 时 ,含量最高 ,高于 5 .0 mg/ L 时 ,茄红素含量急剧下降 ;2 ,4-D浓度在 0 .0～ 0 .1 mg/ L范围内 ,浓度增加有利于细胞鲜重和茄红素总产量的提高 ,浓度高于 0 .1 mg/
The effects of 2,4 D concentrations on lycopene synthesis by carrot (Daucus carota L) cells in suspension were studied by measuring the changes of the lycopene content, total cell fresh weight and total lycopene yield with the 2,4 D concentrations in medium.The results showed that 2,4 D had great effect on lycopene synthesis. The lycopene contents increased with the concentrations increment from 0.0 mg/L to 5.0 mg/L, and declined deeply as the concentrations higher than 5.0 mg/L . The value of lycopene content at 5.0 mg/L was the highest of all treatments. The total cell fresh weight and total lycopene accumulation were all improved with the concentrations changing from 0.0 mg/L to 0.1 mg/L.
