【摘要】 用高压静电场分别处理干的水稻种子和30℃预浸种吸水24 h的水稻种子,计算种子的活力指数、发芽指数、幼苗干重,研究电场处理对2种水稻种子活力的影响是否有差异.结果表明:水稻种子吸水24 h后,种子吸胀结束,开始进入萌发阶段,经电场处理后种子的发芽指数、幼苗干重和活力指数显著高于对照.而经电场处理的水稻干种子活力与对照相比无显著差异.种子的吸水程度显著影响高压静电场对水稻种子的生物学效应.更多还原

【Abstract】 The effect of the high electrostatic field(HVEF) on rice seeds was studied.The seeds included the dry seeds and the wet seeds which were sopped for 24 hours at 30℃ before the HVEF treatment.The results show that the seeds finished imbibition and germinated after being sopped for 24 hours.The germination velocity,vigor index of wet seeds and the dry weight of seedings are significantly increased after appropriate treatments.But HVEF slightly affect the seed vigor of the dry seeds,instead,the vigor of dry seeds decrease after treatment.The moisture content of the seeds highly affect the biological effects of HVEF on rice seeds.更多还原
