Tymochko I. Forestry and Ecological Features and Coenopopulations State of Allium ursinum L. in the Forests of the Precarpathians

Research object - coenopopulations of wild onion in Precarpathians conditions. Goal - to establish forestry dissemination of wild onion in Precarpathians, to examine its ecological and biological characteristics, population structure and develop the scientific basis of rational use and preservation. Research methods - methods of experiment, observation and analysis, and the following methodics: Forest-taxation, biometric, phenologic, phytocoenotic, phytosozologic, phytochemical and mathematic statistics. Scientific novelty - Based on comprehensive research of wild onion populations in Precarpathians conditions are established distribution peculiarities and studied eco-phytocoenotic features and structure of species populations in natural growth conditions, firstly established phenological spectrum of species individuals development, which lasts an average of 127 days for a total value of effective air temperatures 1234-1330 C; - In a conditions of wet soils in leaves of wild onion during the vegetation period are revealed reduction of lead, copper and cobalt and increased zinc, manganese and potassium; are studied the biotic stability of its biological specimens in different types of forest conditions before damaging by diseases and pests. Practical significance. The obtained results of research have both as theoretical so practical importance. The author found the forestry and environmental features of the distribution and structure of coenopopulations of wild onion and elaborated practical recommendations on rational use and protection of the studied species. Research results could be the basis for the monitoring organization of coenopopulations state of wild onion and used in subsequent editions of the Red Book of Ukraine, references of rare plants and in the study process. Field of use: forestry.
