Abstract
Greening the urban environment is a necessary element for improving the quality of life of the population, which requires the use of significant amounts of seedlings of flower-ornamental plants. Soil condition in greenhouse complexes does not always meet the requirements, which causes low yield and quality of grown plants. Phytotesting and assessment of ecological quality of soil in greenhouse complex were carried out through research of oxidative enzymes activity. The control of the level of toxicity and chemical contamination of soil is necessary for the development of measures to reduce and prevent changes in the soil and biotic environment. The comprehensive study of soil has revealed factors affecting its quality and suitability for growing flower crops. Dynamic changes in biological indices are recorded during phytotest of soil, as well as during control of level of enzymatic activity of oxidative enzymes. An average and low level of phytotoxicity of the studied soil is established, as well as inhibition of activity of enzymes: catalase, ascorbatoxidase, peroxidase. The soil survey in the greenhouse complex showed that for rapid diagnosis of its condition it is possible to use both phytotest of samples, to carry out analysis of the level of activity of oxidative enzymes.
