Effect of 2 MHz ultrasound irradiation on Pisum sativum roots
Journal Article
·
· Radiat. Res.; (United States)
The effect of 2 MHz ultrasound at intensity levels from 2.5 to 22 W/cm/sup 2/ on the growth rate and mitotic index of Pisum sativum roots was studied. The ultrasound produced an immediate reduction in the growth rate on the first postexposure day, followed by a gradual recovery to the control value. Ultrasound reduced the root meristem mitotic index. Intensity- and time-dependent relations were found for the growth rate and mitotic index reductions. (auth)
