MORPHO-ANATOMICAL AND ECOLOGICAL FEATURES OF THE SPECIES OF THE GENUS JUGLANS L. IN THE CONDITIONS OF BELGOROD REGION

For the first time, the study of morphology and biology of six species of the genus Juglans L .: J. regia L., J. mandshurica Maxim., J. sieboldiana Maxim., J.cinerea L., J. nigra L., J. rupestris Engelm was conducted in the conditions of the Belgorod region. Rhythm of seasonal development, drought tolerance and yields were identified. Leaf trichomes of six species of the genus Juglans L. were described. A preparation method of leaf epidermis of the genus Juglans L was modified. New data on quantitative and qualitative indicators of fruits was observed including: morpho-structural components, productivity and tolerance to unfavorable conditions in the Belgorod region. Morpho-anatomical structure of the leaves was studied by using the SEM Quanta 200 3D, the Carl Zeiss microscope.
