The influence of electric transmission lines on fluctuating asymmetry of goat willow

The aim of the investigation is to determine the index of fluctuating asymmetry (FA) of goat's willow plants growing under high-voltage transmission lines and in areas subjected to pollution of atmospheric air by automobile emissions. The plants grew on the site located under 220 kV transmission line in suburban green zone of Krasnoyarsk in Nikolayevskaya Sopka area (experiment 1); at the section located under the 500 kV transmission line, 25 km from Krasnoyarsk near the Ryabinino railway station (experiment 2) and on the territory along the city road (experiment 3). To estimate the level of contamination of the latter, the number of cars passing along the road for 1 hour was calculated. Control 1 was represented by a section of suburban zone, located more than 100 m from 220 kV transmission line. As control the site which was more than 100 m from 500 kV transmission line was selected. In plants growing in these areas, the width of the left and right sides of the leaf was measured and index value of FA was calculated...
