Industrial soil pollution with heavy metals, sulphur, fluorine, chlorine, etc. has become
important environmental factor that significantly affects plant organisms, causing their
oppression. In this regard, we have studied the reaction of seven species of ornamental
plants (Ageratum houstonianum cv. Bule Lagoon, Dahlia variabilis Desf., Echinacea
purpurea L., Dahlia variabilis Desf., Calendula officinalis L., Cosmos sulphureus Cav., Agrostemma githago L., Atnplex hortensis L., Linum usitatissimum L., Petunia Hybrida
Grandiflora L.) on contamination of the soil by sulphur and fluoride.
Significant negative impact of pollutants on the accumulation of wet and dry mass by
all studied plant species has founded. So, plants Atnplex hortensis, Calendula officinalis,
Dahlia variabilis, Echinacea purpurea and Petunia Hybrida are characterised by considerable
(20,4–79,1 %) inhibition of the accumulation of green and dry mass in compared to
plants grown in soil without any pollutants. Whereas in Agrostemma githago, Cosmos sulphureus,
Linum usitatissimum and Ageratum houstonianum significant changes in the accumulation
of green and dry mass of seedlings in dirt haven’t observed.
There is a tendency to inhibition of wet mass in the plants by 18,7–24,7 %, which may
indicate significant impairment of the synthetic processes and the water balance of plants
at high doses of pollution. The common cockle Agrostemma githago, Cosmos sulphureus,
Linum usitatissimum were the most resistance on results of the study.
