利用匀强电场对杉木当年生茎段外植体进行处理,研究电场强度和处理时间对杉木茎段芽诱导的影响。在1.0 k·Vcm -1的电场强度下处理5 min,芽诱导率最高,达100%,比对照组增加62.50%;芽形成能力达835.00%,是对照组的2.78倍,亦高于其它处理组合;平均芽数最高达到12.50个,是对照组的2.50倍,与对照组具有显著差异。7.0 kV· cm -1电场强度处理1 min后,随着处理时间的增加,诱导率均为0,明显抑制了杉木芽的分化;处理3 min后,外植体存活率均呈下降趋势,致死作用增大。结果表明:电场强度和处理时间对杉木外植体的芽诱导率和形成能力具显著影响。
利用勻彊電場對杉木噹年生莖段外植體進行處理,研究電場彊度和處理時間對杉木莖段芽誘導的影響。在1.0 k·Vcm -1的電場彊度下處理5 min,芽誘導率最高,達100%,比對照組增加62.50%;芽形成能力達835.00%,是對照組的2.78倍,亦高于其它處理組閤;平均芽數最高達到12.50箇,是對照組的2.50倍,與對照組具有顯著差異。7.0 kV· cm -1電場彊度處理1 min後,隨著處理時間的增加,誘導率均為0,明顯抑製瞭杉木芽的分化;處理3 min後,外植體存活率均呈下降趨勢,緻死作用增大。結果錶明:電場彊度和處理時間對杉木外植體的芽誘導率和形成能力具顯著影響。

Chinese fir seedling stem section of explants was treated by the uniform electric field , and the impact of different electric field intensity and different processing time on bud induction of Chinese fir stem section was investigated .Bud induction rate was 100%under the electric field intensity as 1.0 kV· cm-1 for 5 min, increasing 62.50 percent compared with the control group .The capacity of bud formation was 2.78 times that of the control group , up to 835.00%, also higher than other treatment combinations . The average number of buds reached the highest as 12.50, 2.50 times as that of the control group .Under the electric field intensity as 7.0 kV· cm-1 for 1 min, with the increase of processing time , bud induction rate was 0, and the inhibitory effect on bud differentiation was remarkable , after 3 min, the survival rate of explants were decreased , and lethal effect on explants was increased.The results indicated that the bud induction rate and forming ability of Chinese fir explants were affected by electric field intensity and the processing time significantly .
