超声对猕猴桃溃疡病的抑制作用
Inhibitory Effect of Ultrasound on Kiwifruit Bacterial Canker
摘要
Abstract
Pseudomonas syringae pv.actinidiae(Psa)was treated in vitro by setting different ultrasonic frequencies and ultrasonic durations.The number of viable bacteria and respiratory chain dehydrogenase activity of Psa were detected after treatment,and the ultrasonic treatment conditions with better bacteri-cidal effect were screened.Secondly,the detached branches of Xiangjihong and Beimu after Psa infection were treated with ultrasonic waves under different conditions.After 30 days of culture,the size of canker lesions was detected to explore the inhibitory effect of different ultrasonic conditions on kiwifruit canker.The results showed that 60 kHz ultrasonic treatment for 45 min or 80 kHz ultrasonic treatment for 15 min could control the lesion of Beimu branches to about 2 cm.Treatment with 80 kHz for 30 min could control the lesion of Xiangjihong branches within 2 cm,and completely inhibit the infection of can-ker spot on the Beimu branches.关键词
