| 摘 要： | 应用电子顺磁共振(ESR)波谱仪对磁场处理过的芝麻种子连续14d跟踪测量,结果表明磁场可促进芝麻种子内部自由基浓度增加,且其自由基浓度随贮藏时间的延长明显降低,14d后其自由基浓度降低30%以上。用最佳磁场强度分别对芝麻种子进行12min、24min、36min、48min和60min不同梯度处理,结果表明电流50A(磁场强度835G)的磁场处理芝麻种子36~48min生物效应最佳,能有效提高芝麻种子发芽率和发芽势,促进根系生长。

| Abstract: | The electron spin resonance was used to trace the free radical concentration in the seed of Sesamum indicum treated with magnetic field once a day for 14 days.The results show that the free radical concentration in the Sesamum indicum seeds increases with the magnetic field treatment,and decreases obviously with the prolongation of storage period and loses more than 30% 14d later.The experiments with the optimum intensity of magnetic field(835G) to treat Sesamum indicum seeds for 12min,24min,36min,48min and 60min demonstrate that the treatment time between 36 and 48min can get an ideal biological effects. |
