Abstract
The research was conducted in 2005-2008 in Krakow. The experiments were located close to three busy streets of the city: Igołomska, Lublańska and Mickiewicz Avenue. The experiment aimed at determining the effect of pre-sowing stimulation of red fescue seeds with a laser diode on heavy metal contents. After four years of red fescue exposure along the three streets in Krakow a smaller soil pollution with heavy metals was assessed in the pots sown with the grass sowing material which was pre-sowing stimulated with the laser diode. Computed bioaccumulation coefficients (BC) revealed that the red fescue which was pre-sowing stimulated with the laser diode accumulated higher quantities of all analyzed heavy metals than the plants which were not stimulated before sowing. Red fescue, both stimulated with the laser diode before sowing and without the pre-sowing stimulation absorbed greater quantities of copper, zinc, cadmium and nickel, but smaller amounts of chromium and lead.
Description
The research was conducted in 2005-2008 in Krakow. The experiments were located close to
three busy streets of the city: Igołomska, Lublańska and Mickiewicz Avenue. 16 objects were set
up at each location (2 variants in 8 replications). The experimental objects were pots with red
fescue, Raisa c.v. 24 pots contained the plants which before sowing were stimulated with a green
light emitted by the laser diode, three times for 30 seconds, whereas the remaining 24 pots were
sown with red fescue sowing material without previous irradiation.
The experiment aimed at determining the effect of pre-sowing stimulation of red fescue seeds
with a laser diode on heavy metal contents. After four years of red fescue exposure along the three
streets in Krakow a smaller soil pollution with heavy metals was assessed in the pots sown with
the grass sowing material which was pre-sowing stimulated with the laser diode. Computed bioaccumulation
coefficients (BC) revealed that the red fescue which was pre-sowing stimulated with
the laser diode accumulated higher quantities of all analyzed heavy metals than the plants which
were not stimulated before sowing. Red fescue, both stimulated with the laser diode before
sowing and without the pre-sowing stimulation absorbed greater quantities of copper, zinc, cadmium
