Аннотация:In this work the biological effects of three fine-dispersed materials, namely metallurgical
sludge, polyhexamethylene biguanide (PHMB) stabilized colloidal silver and multi-wall carbon
nanotubes (MWCNT) on oilseed rape plants are described. The stimulation of plant growth by
silver nanoparticles and the intensification of plant pigments synthesis by MWCNT have been
experimentally demonstrated. A small decrease in energy and germination capacity were noticed
whereby colloidal silver had the lowest suppressive effect, MWCN tubes had the highest effect, and
the sludge could be placed between two above-mentioned materials. According to the research, the
usage of sludge is the most effective at the concentration of 10 and 100 g/l, PHMB-stabilized
colloidal silver – 0.5 mg/l (0.5 ppm) and 15 mg/l (15 ppm), MWCNT – 0,001 g/l and 1 g/l.
