Growth And Development

The effect of diatomite and tripoli added into the soil artificially contaminated with benzo[a]pyrene was studied. A decrease in the toxic effect of BaP on barley plants was established when diatomite and tripoli were added as ameliorants to contaminated soil. The improvement of plants grown сharacteristics on soils contaminated with BaP with the addition of diatomite and tripoli was shown up to 2-4 times compare to contaminated samples.

Positive Effect

The effect of various doses of diatomite introduced into soil artificially contaminated by benzo[a]pyrene was analyzed. The negative effect of benzo[a]pyrene on the growth of barley (Hordeum sativum distichum) seedlings and reduction of toxic effect of polyarene on plants after implementation of diatomite as a sorbent into contaminated soil are shown. A significant increase (by 2–3 times) of the plant growth in contaminated soil with the addition of diatomite has been revealed. The introduction of 2.5% diatomite into contaminated soil had the significant positive effect on barley seedlings.

Metal Treatment

In this study, the effect of cadmium metal ion to 7, 14 and 21day after germination (DAG) autumn barley samples under laboratory condition is investigated. We determined the biomass of plant organs and the amount of cadmium accumulation in above-ground organs at germination (7 DAG), 2-leaf (14 DAG), 3-leaf (21DAG) stages. The results showed that the dry mass of 7, 14 and 21 DAG barley plant was decreased under cadmium metal treatment. However, the root biomass did not change compared with control plant. It is also observed that the 21 DAG plant accumulated around 2.4 and 5.6 times more cadmium than the 14 DAG and 7 DAG plants respectively.

The results of an experiment on cleaning oil-contaminated soil and accelerating the restoration of its fertility with the aid of combined biopreparations containing bacteria that degrade oil and microorganisms that can stimulate the growth and development of plants. It is shown that the introduction of bacterial mixtures reduced the oil content by 3.1–3.6 times and increased by 2-3 orders the number of basic physiological groups of soil microorganisms participating in its transformation, and also accelerated the germination of seeds (for 2 days) and the beginning (for 6–7 days) of all stages of oat development, used as a phytomeliorant. The most effective was a biopreparation consisting of a consortium of microorganisms Acinetobacter calcoaceticus IB DT-5.1/ 1 and Ochrobactrum intermedium IB DT-5.3/2 and strains of Pseudomonas koreensis IB-4 and Paenibacillus ehimensis IB 739, which, among other things, increased the mass of oat shoots in 2.3–2.6 times and their length is 54.0–77.8% compared to plants in the soil untreated with bacteria with oil.
