RESUMO
THE PURPOSE OF THIS STUDY: Is a comparative assessment of the phytoncidity of woody plants of different botanical families and genera and the selection of taxa with a pronounced, long-term, and universal antimicrobial effect for use in greening and landscape construction in sanatorium-resort practice. MATERIAL AND METHODS: The objects of research were 167 species, hybrids, and intraspecific forms of woody plants from 25 botanical families and 16 genera. Evaluation of phytoncidity was carried out using the method of treating streak inoculation of microbial test cultures with volatile emissions of leaves; gram-positive bacteria Staphylococcus epidermidis (ATCC 25923), gram-negative bacteria Escherichia coli (ATCC 25922) and yeast-like fungi Candida albicans (ATCC 10231). RESULTS: It was established that woody plants of different taxonomic affiliations differ in the degree of antimicrobial activity, most of the studied taxa are characterized by seasonal variation of the studied trait. It was revealed that 102 (61.1%) of the species, form and hybrid are distinguished by pronounced activity to yeast-like fungi C. albicans, 64 (38.3%) - to E. coli and 33 (19.7%) - to bacteria St. epidermidis. The highest antimicrobial activity was recorded in representatives of the genera Salix, Populus, Amelanchier, Prinsepia, Prunus, Rosa, Spiraea, Picea, Pinus, Thuja, Juniperus, Caragana, Acer, Syringa. CONCLUSION: Based on the data obtained, 54 species, a hybrids, and a forms with a pronounced antimicrobial effect were identified, 21 with a long-lasting and 5 with a universal effect. The results can be used for landscaping resort and health areas in the Siberian region.
