摘要
为了探索超声波处理对国槐种子萌发的影响,利用47、59KHz超声波对国槐种子进行了超声波处理。结果表明:用59KHz超声波处理种子10min效果最好,可以使国槐种子萌发率提高及发芽指数分别提高44.3%;59KHz超声波处理种子5min后可溶性糖含量比对照值提高32.5%,淀粉含量提高7.96%;处理时间大于25min,会明显降低种子淀粉含量;超声波处理对种子电导率及可溶性蛋白质含量没有明显的影响。
To probe into the effects of Ultrasonic wave on germination of Sophora japonica seeds, the experimentation were done on Sophora japonica seeds that were treated with 59 KHz,47 KHz Ultrasonic wave. The results showed that the seeds treated by 59 KHz Ultrasonic wave for 10 rain had germination rate and germination index 44.3% higher than contrast respectively; the seeds treated by 59 KHz Ultrasonic wave for 5 min had content of soluble sugar and starch 32.5% and 7, 96% higher than contrast respectively,and Ultrasonic wave treatment more than 25 min reduced in evidence the content of starch in seeds in germination;and Ultrasonic wave treatment did not change the content of soluble protein and relative conductivity of Sophia japonica seeds treated.
