摘要
以甘草为试材,采用高压静电场处理甘草种子的方法,研究了电压及处理时间对甘草苗期几项生理生化指标的影响。结果表明:电场处理降低了苗期的相对含水量、提高了苗期的根冠比、根长和株高。随着甘草苗龄的增加,整体上叶绿素a含量18kV组高于对照组,15kV组低于对照组;整体上叶绿素b含量18kV组在前45d高于对照组,45~90d低于对照组,而15kV组一直低于对照组。电场处理组的可溶性蛋白含量在30~75d低于对照组,75~90d整体略高于对照组。
Taking licorice as test material by high voltage electrostatic field,physiological and biochemical indexes which influenced by different voltage and processing time during licorice seedling stage were studied.The resultsshowed that the high voltage electrostatic field reduced relative water content and increased root shoot ratio and root length and plant height of seedling stage licorice;with the increase of licorice seedling age,the content of chlorophyll a increased first and then decreased.The 18 kV group was higher than the control group while the15 kV group was inverse.And the content of chlorophyll b in the 18 kV group was higher than control group at the first 45 days then lower than the control group during 45-90 days,while the 15 kV group was always lower than the control group;the content of soluble protein in high voltage electrostatic field treated group was lower than control group during 30-75 days but higher than control group during 75-90 days.
