Morphological and anatomical study of flowering shoots of Crataegus flabellatа (Bosc ex Spach) K. Koch

Aim – to carry out a morphological and anatomical study of Crataegus flabellata (Bosc ex Spach) K. Koch. Material and methods. Leaves, shoots and flowers of the Crataegus flabellata collected at the flowering stage in the Botanical Garden of Samara University were used in the work. Micro-preparations of air-dry raw materials were immersed in an alcohol-water-glycerin mixture (1:1:1). Microscopic examination was carried out in transmitted and reflected light using a Carl Zeiss Primo Star 415500-0057-000 digital microscope (Imaging Software for Microscopy ZEN core V2.7). Results. The study of anatomical and morphological properties of dried flowering shoots showed that the most characteristic feature of the shoots Crataegus flabellata (Bosc ex Spach) K. Koch is the presence of multicellular glands and simple unicellular hairs along the edge of leaf plates, bracts and sepals. In addition, the number of stamens in the flower is from 5 to 12. Conclusion. Microscopy of dried flowering shoots of the Crataegus flabellata (Bosc ex Spach) K. Koch was described for the first time. The morphological and anatomical analysis of flowering shoots of Crataegus flabellata (Bosc ex Spach) revealed similarities and differences with other species of the genus (Crataegus L.).
