The effects of ultrasonic waves, microwaves, thermal stress, thermal stress combined with ultrasonic waves and thermal stress combined with microwaves on the germination of Tartary buckwheat seeds from Ningxia and Sichuan were compared. On the seventh d of germination, the highest germination rate of Tartary buckwheat from Ningxia treated with ultrasonic waves was 87.33%, which was 4.66% higher than that of the control (p < .05). The highest germination rate of the microwaves treatment of Tartary buckwheat from Sichuan was 86.67%, which was 4.67% (p < .05) higher than that of the control. The ultrasonic waves and microwaves treatments increased the content of flavonoids and reducing sugars and enhanced the DPPH and ABTS radical scavenging activities. In addition, the ultrasonic waves and microwaves treatments had positive effects on the activities of catalase and phenylalanine ammonia lyase.

超声波，微波和热胁迫处理对苦荞种子发芽的影响

比较了超声波，微波，热应力，热应力与超声波，热应力与微波结合对宁夏和四川苦荞种子萌发的影响。在发芽的第七天，用超声波处理的宁夏苦荞麦的最高发芽率为87.33％，比对照高4.66％（p  <.05）。四川art苦荞的微波发芽率最高，为86.67％，最高为4.67％（p <.05）高于对照组。超声波和微波处理增加了类黄酮和还原糖的含量，并增强了DPPH和ABTS自由基清除活性。另外，超声波和微波处理对过氧化氢酶和苯丙氨酸氨裂合酶的活性有积极的影响。
