Sliusar H. Biological features of Schisandra chinensis (Turcz.) Baill. for introduction in the Right-Bank Forest-Steppe of Ukraine

The dissertation is devoted to the study of biological features of tree vines S. chinensis (Turcz.) Baill. in the conditions of introduction in the Right-Bank Forest-Steppe of Ukraine. The rhythms of growth and development of plants, regularities of flowering and fruiting have been studied, the duration of the vegetation period of Chinese magnolia and the duration of the dormancy period have been determined. It is established that in the conditions of introduction the beginning of vegetation of plants is noted a month earlier in comparison with the conditions of the natural range (Kolbasin). It is established that the rhythms of seasonal development of plants correspond to the natural and climatic conditions of introduction. Winter-frost and drought resistance of plants in field and laboratory conditions were determined. On the basis of a comprehensive study of biochemical and anatomical and morphological features of plants, adaptations to environmental stressors were found. The analysis of the obtained results showed that the plants have high plasticity and are promising for cultivation in the study area. Methods of seed and vegetative reproduction are analyzed. It is established that the optimal methods of seed propagation of lemongrass is the spring hanging of stratified and autumn sowing of freshly harvested seeds, which provide soil similarity of 65 and 62,5%, respectively. On the basis of experimental data the elements of the protocol of technology of microclonal reproduction of a magnolia tree are developed. The biochemical features of vegetative and generative organs of plants under the conditions of introduction have been studied.
