【摘要】 研究了负高压静电场处理甘草(licorice)种子,对其萌发的影响。用不同强度的负高压静电场(E=3nkV/cm,n=0,1,2……9),不同的处理时间(T=5nmin,n=2,3,4,5)及不同的处理种子的方法(a.直接电场处理;b.浓硫酸浸泡后电场处理)来处理甘草种子,检测甘草种子的发芽率,并对实验数据进行单因素方差及LSD多重比较法分析,设置空白组进行对照。实验结果表明:处理1在E=27kV/cm,T=10min时发芽率最高,发芽率为(42.33±1.53)%且表现出极显著性;处理2在E=18kV/cm,T=25min时发芽率最高,发芽率为(80.67±1.15)%且表现出极显著性,从整体上看由浓硫酸浸泡后电场处理的甘草种子远高于直接电场处理的甘草种子的发芽率。更多还原

【Abstract】 This article studied the negative high electric field to process the licorice seed,and its influence on the germination.The different negative high electric field(E=3nkV/cm n=0,1,2……9),the different processing time(T=5n min n=2,3,4,5)and the different processing methods of seed(1,processing it for direct electric field;2,after immersing in 98%sulfuric acid then processing it for electric field)to process the licorice seeds,then measures the germination rate.The experimental data by single factor analysis of variance and then LSD multiple comparisons to analyze.This experiment sets comparison groups.The result indicates that processing 1has highest germination rate under the E=27kV/cm,T=10min electric,seeds germination rate is(42.33±1.53)%,and it shows the most significant,Under the E=18kV/cm,T=25min,seeds germination rate of processing 2is highest,It is(83±4.24)%,and difference is the most significant.Overall,The germination rate that after immersing in 98% sulfuric acid then processing licorice seeds is higher than electric field process licorice directly.更多还原
