Effect of Ultrasonic Vibrations on Plant Growth,

Abstract

Earlier studies on the effects of ultrasound on plant growth failed to specify the intensities of ultrasonic vibrations in USSR. This study examines the effect of ultrasound with specified intensity, exposure time, and frequency on the seeds of several plant species. Germination rate and plant growth are shown to be either stimulated or inhibited, depending on the conditions of ultrasound exposure. (Author)
