Sytnik S. Bioecological features of representatives of family Myrtaceae R.Br. at an introduction on Southern coast of the Crimea

Research subjects: Species of family Myrtaceae from collection of the Nikita botanical garden. Research objectives: To reveal bioecological features of representatives of family Myrtaceae of a various geographical origin at an introduction on Southern coast of the Crimea in connection with prospect of their rational use. Methods: morpho-anatomic methods, phenological observations, chromatographic methods. The assessment of success of an introduction is specific by a method of "number of an acclimatation " Theoretical and practical results: Results of an introduction of representatives of family Myrtaceae on the Southern coast of the Crimea are generalized and the assessment of its success is spent. It fixed, that the highest degree of acclimatization characterizes polymorphic mesophytic species Myrtus communis, xeromezophytes Acca sellowsana, hemixerophytes pecies of gender Callistemon. 22 monoterpenic components of an essential oil from leaves Myrtus communis, 25 phenolic connections of an extract from leaves Myrtus communis are identified. Responsive microorganisms to specific substances of an extract from leaves Myrtus communis fixed. Novelty of introduced: For the first time laws of rhythms of growth and development of representatives of family Myrtaceae which grow on Southern coast of the Crimea are revealed. On rhythms of growth and flowering phenological groups are secured. For the first time on a complex of morpho-anatomic structures of a leaf ecological groups are specific: mesophytes, xeromezophytes, hemixerophytes, xerothytes. Substantial seed production of a family Myrtaceae is specific at an introduction on Southern coast of the Crimea. The highest parameters of substantial seed production at hemixerophytes species of gender Callistemon. Maximal accumulation of an essential oil in leaves of polymorphic species Myrtus communis var. leucocarpa descends in a budding stage Implementation degree: To department of a dendrology for the further introduction 100 plants Myrtus communis are transmit. Kinds for green construction and an ornamental gardening, building of improving compositions in parks and sanatorium complexes of the Southern coast of the Crimea are recommended. Results of dissertational work on research of biology of species of family Myrtaceae are used in educational process of National Pharmaceutical university. Effectiveness: It fixed optimal times, and parameters of temperature for crop of seeds of a family Myrtaceae allow to intensify cultivation of a planting stock for use in green construction on Southern coast of the Crimea. Sphere, sector of implementation: botany, green construction, silviculture, pharmacology, specialists training.
