TERATOGENESIS OF PINE SEEDLINGS AS BIOINDICATOR OF SOIL CONTAMINATION IN FOREST NURSERIES BY PESTICIDES

The results of the study of teratogenesis pine seedlings caused by the use of pesticides in nurseries of forest and forest-steppe zone of the Ural region have described. Series of experiments by study the effect on pine TMTD, fundazol, 2,4-D and Roundup and degree of display the teratogenesis on pine by using chemicals separately and in combination were carried out. And also studied the influence on teratogenesis of pine the exceeding of recommended pesticide dose. Impact on the seedlings of each pesticide was studied in small plot experiments. At the end of experiment 2-year-old pine seedlings were dug up and divided into groups according to the morphological structure (phenotype). Pesticide residues in the soil and in seedlings was determined by gas chromatography. It is found that a violation of the morphological status of pine seedlings under the influence of both individual pesticides and their complex has a distinct character, so the teratogenesis of pine seedlings can be used as a bioindicator on presence of chemical contamination of the soil.
