| 摘 要： | 利用正交试验设计和主成分分析方法研究了高压脉冲电场对番茄陈种子萌发的影响.结果表明:高压脉冲电场可以促进番茄陈种子萌发,提高种子的发芽率、发芽势、发芽指数和活力指数,尤其以发芽势的提高最为显著.通过对试验资料的正交设计方差分析,可以得出对种子萌发影响最大的因素是种子干湿情况,其次是场强,影响最小的因素是作用时间;当电场强度是8 kv/cm,作用时间是180 s,作用种子为湿种子,高压脉冲电场对种子的作用效果最好.高压脉冲电场处理的陈种子中过氧化氢酶、过氧化物酶和超氧化物歧化酶的活性增强,明显高于对照种子.

| Abstract: | The article used statistical method of orthogonal design and main principal component analysis analyzed the effect of on old tomato seeds during sprouting process of seedling.The results showed that germination percentage,germination energy,germination index and vigor index of old tomato seeds were increased,and enhancements of germination energy were greater.From orthogonal design analysis of variance,we could conclude that the influencing order was that water contents of seeds,strength field and times.Old seeds treated by PEF increased activities of catalase,Peroxidase and Superoxide dismutase.We can conclude from analysis that the best treatment was that old waterish seed treated by high intensity pulsed electric fields of field strength was 8 kv/cm and times was 180 seconds. |
