Aim of study (acc. to author)

A sensitive clone of Spirodela polyrhiza (L.) Schleiden was used as a test organsim to study the effects of the Skrunda Radio Location Station in Latvia.

Main outcome of study (acc. to author)

The vegetative reproduction rate was accelerated in the first 20 days after the end of exposure. Exposure of plants just beginning formation lowered the vegetative growth rate. At 55 days, various morphological and developmental abnormalities appeared in 6-10 daughter plants from 10 exposed mother plants, compared with 0.1 plants per 10 in the control condition. Plants developed completely to daughter fronds under exposure from electromagnetic field had a shorter life-span and a fewer subsequent daughters.
