| 摘 要： | 研究了不同电场剂量处理细枝岩黄芪种子对其愈伤组织诱导率和分化率的影响。结果表明,电场处理可以明显提高愈伤组织诱导率和分化率。电场强度为7kV/m,处理时间为100min,诱导培养基为MS+2,4-D 2.0mg/L+6-BA 1.0mg/L时出愈率可达91.0%,且生长情况较好,褐变程度轻。在MS+2,4-D 2.0mg/L+6-BA1.0mg/L诱导培养基上继代培养后的各愈伤组织分别转移到分化培养基上进行分化培养,当电场强度为7kV/m,时间为100min时分化率最高,达到78.3%。 |

| Abstract: | Abstract：The seeds of Hedysarum scoparium Fisch.et Mey. were treated by electrical field at different doses, the effect on the callus inductivity and differentiation rate were studied. The results showed that electrical field treatment could increase the callus inductivity and differentiation rate, when the field strength was 7kV/m, treating time was 100min and the inducing media was MS+2, 4 D 20mg/L +6 BA 10mg/L, the callus inductivity was 910% with low browning rate. The callus differentiation rate 783% on the medium with MS+6 BA 20mg/L+NAA 02mg/L with field strength of 7kV/m and time of 100min was the highest. |
| Keywords: | Hedysarum scoparium Fisch et Mey radiation with electrical field callus inductivity differentiation |
