超声波对灰毡毛忍冬种子萌发能力的影响

研究超声波的处理时间、温度、功率对灰毡毛忍冬(Lonicera macrathoides Hand.-Mazz.)种子萌发能力的影响,寻找其超声波处理的最佳组合,为提高灰毡毛忍冬种子的发芽势和发芽率提供理论依据。在适宜的温度、湿度和充足的氧气条件下,进行常规的种子萌发试验,统计灰毡毛种子在不同组合的超声波处理时间、温度、功率条件下的发芽势和发芽率。灰毡毛忍冬种子经适当的超声波处理,可以提高其发芽势和发芽率,正交试验发现10 min、40℃、40 W的超声波处理条件最适宜于灰毡毛忍冬种子的萌发。超声波可以打破灰毡毛忍冬种子的休眠,提高其发芽势和发芽率。

The effects of Ultrasonic Wave (UW) on the seed germination ability of Lonicera macrathoides Hand.-Mazz.

To study the effects of UW treatment time, temperature and power on seed germination ability of Lonicera macrathoides Hand-Mazz, then find the best combination of ultrasonic wave treatment in or- der to provide theoretical basis for germination potential and rate of Lonicera macrathoides Hand.-Mazz. Seed. In the appropriate temperature, humidity and oxygen-rich environment, a conventional seed ger- mination experiment was conducted to calculate the seed＇s germination potential and rate under different combination treatment. Results： The potential and the rate of germination of the seed of Lonicera macrathoides Hand.-Mazz. were both improved by appropriate ultrasonic wave treatment. The orthogonal test shows that the best germination condition for Lonicera macrathoides Hand.-Mazz. seeds was treated by 40W ultrasonic wave treatments at 40℃ with 10 minutes. Conclusion： The ultrasonic wave can break the dormancy and improve the potential and the rate of germination of Lonicera macrathoides Hand.- Mazz seed.
