abstract:
The aim of the conducted research was to define the influence of electromagnetic field on the length and mass of pine needles and increase in tree height. Conifer material was taken from three-year-old pine cultivation within five research transects at distances of 10 m, 20 m, 30 m, 40 m and 50 m from the power transmission line. Statistical analysis proved that pine trees growing within a distance of 30 m from electrical power line had smaller length and lower assimilating apparatus mass. Relatively to trees growing in transects outlying about 40 m and 50 m, a lower overall height was also noted.
