摘　　要：以南方4种针叶树种(杉木、马尾松、湿地松、火炬松)种子为研究对象,采取自主设计的高压静电种子处理装置,设置不同的电场强度(1.5、2.5、3.5、4.5、5.5 k V·cm-1)和处理时间(5、10 min),及不经电场处理的对照组(CK),探讨不同电场处理对杉木、马尾松、湿地松和火炬松干、湿种子萌发规律的影响。结果表明:对4种树种干种子施加不同电场强度处理后,只有马尾松干种子发芽势、发芽率和火炬松干种子发芽势在处理10 min时存在显著影响(P<0.05),其它树种干种子发芽势和发芽率在各处理条件下均无显著影响(P>0.05)。而4种树种湿种子经不同电场强度处理后,除了杉木湿种子发芽势和马尾松湿种子发芽势和发芽率在不同处理时间下有显著影响(P<0.05),其它各树种湿种子在各处理条件下均未达显著水平(P>0.05)。The research object is the South 4 coniferous species（fir,pine,slash pine,loblolly pine）seeds,apply for high-voltage elec-trostatic seed processing device independent design ,set different electric field strength（1.5,2.5,3.5,4.5,5.5 kV· cm-1）and pro-cessing time（5,10 min）,and not by the electric field treated control group （CK）,to explore different electric field treatment on fir , pine,slash pine and loblolly pine dry and wet laws affecting seed germination.The results show that After four kinds of different spe-cies of dry seed applied electric field strength ,only Masson pine dry seeds germination rate and loblolly pine dry seed germination potential significant impact on treatment （ P〈0.05 ） exists 10 min,the other species of seed germination potential and dry rate of no significant impact （ P〉0.05 ） in each treatment condition.The four kinds of tree seeds after wet processing different electric field strength,in addition to the wet fir and Masson pine seed germination energy and germination rates have a significant effect （ P〈0.05 ） at different processing time ,other tree species in the wet seed treatment under the conditions did not reach significant levels （ P〉0.05 ）.
