Volodarets S. Sanitation Function of the Woody Species in Cultivated Phytocoenosis of the Urban Environment.

The object is phytoncide activity of the woody species in cultivated phytocoenosis of the south-east of Ukraine. The aim is to evaluate of the sanitation function of the woody species in the composition of the woody species in cultivated phytocoenosis of the south-east of Ukraine. Methods: microbiological, physiological, phenological observations, experimental and statistical. It is investigated the dust removal function and the phytoncide activity of the volatile organic compounds from leaves of the woody species with their functional states under condition with different types of air contamination. It is proved the increasing antimicrobial and antiprotozoal acivity of the gas-resistant trees in the linear and mass plantings of streets, parcs, sanitation zone of metallurgical, engineering plants and coal industry. It is determined seasonal and daily dynamics of phytonside activity in the conditions of urban environment. It is designed the scale of estimation antiprotozoal activity with test-object Paramecium caudatum Ehr. Practical recommendations are given for estimation sanitation function of woody plants in different types of plantings and further usage of perspective species in the urban environment.
