Pashutina O. The development of perennial Legumes anatomy and morphological adaptability to winter conditions in culture

Research subjects: perennial grasses Fabaceae family: Medicago sativa L., Melilotus albus Medik., Onobrychis viciifolia Scop., Trifolium pratense L. Research objectives: to determine the peculiarities of winter organs development of Medicago sativa L., Melilotus albus Medik., Onobrychis viciifolia Scop., Trifolium pratense L. with the aim of with resistance ability to winter conditions. Methods: anatomy and morphological, polarmetrical, cultivation methods influence, dispersal, correlative and regressive. Theoretical and practical results: geometrical model is proposed for explanation of root movement mechanism The influence of cultivation methods upon root forming and buds development was determined. Novel ty of the introduced: For the first time the nature of buds renewal, forming tillering zone was stated for Melilotus albus Medik., Trifolium pratense L., Medicago sativa L, Onobrychis viciifolia Scop. It was also, stated their terms of sprouting. We have determined and suggested the model of immers ion buds mechanism of perennial food grasses into the soil. On this model basis the method of determination the size roof contraction was worked out in the process of investigation. For the first time new data on lighting intensively influence upon speed of tillering zone development were obtained. Implementation degree: the obtained results on size root contractions, were introduced into students training programs of Lugansk State Agrarian University and Lugansk State Agrarian Pedagogical University after T.Shevchenko. Effectiveness: to raise the yields of perennial legumes plants, selection work as to winter conditions resistance. Sphere, sector of implementation: botany, ecology, feeds production.
