The effect of soil samples contaminated with asymmetric dimethylhydrazine (UDMH) on seed germination, growth and anatomical parameters of seedlings of wild plant species was investigated. The stimulation of seed germination and growth of seedlings of Artemisia dracunculus  and Agropyron pectiniforme with the content of UDMH in soil images 1; 5; 25 mg / kg and 1; 5 mg / kg, respectively,  was established. Whereas,  the germination of seeds and the growth of seedlings of cultivated grass (Tríticum aestívum), the variety – Saratovskaya -29 was inhibited when the UDMH content in soil samples was 5 and 25 mg / kg. Changes in the quantitatively-anatomical structure of the seedlings of Agropyron pectiniforme (upper epidermis of leaf and exoderm, primary root cortex) are consistent with the data of their biotest.Data on the quantitatively-anatomical structure of the leaf and root can be taken into account in further studies of the mechanisms of the influence of UDMH on the growth and development of plants.
