Definition of the degree of stability of decorative floor varieties to copper pollution

An estimation of the phytotoxicity of copper ions for Linum grandiflorum Desf. (cultivar Satin Blue, Blue, Rubrum), Linum perenne L. (cultivar Blue silk, Diamond, Celestial Azure). Compared with the control samples, the inhibition of flax was observed in aqueous experiments already at a concentration of 20 -30 mg/l. The root system was not formed in most varieties at a concentration of 50 mg/l. In soil, in most of the plants under study, significant inhibition was observed at a concentration of 50 mg/kg. Thus, we have identified varieties with high (Rubrum, Diamant, Celestial Azure) and medium sensitivity (Blue, Blue silk) to copper concentrations of more than 50 mg/kg. These varieties can be used in places of low man-caused load (parks, squares, on the adjacent territories).
