Scanning Electron Microscopy in the Analysis of Species of the Genus Persicaria Mill

Introduction. Scanning electron microscopy acts as a promising method of analysis, allowing to describe in detail the identification features closely related plant species, well conduct micro-roentgenstructural analysis sample selected area with high accuracy. The is used study morphology surface and express determination composition elements various fields (physics, materials science, medicine, however, use scanning/raster for raw pharmacy limited. Aim. purpose was species genus Persicaria Mill. using scanning microscopy. Materials methods. objects were maculosa S.F. Gray, hydropiper (L.) Delarbre, tomentósa (Schrank) E.P. Bicknell, mínor (Huds.) Opiz, amphibia var. terrestris (Leyss.) Munshi & Javeid, harvested during flowering Voronezh region. samples by carried out on an microscope JSM-6510LV (Center Collective Use State University). Results discussion. With help microscopy, morphological anatomical signs leaf plates six investigated new diagnostic identified. As result micro-X-RAY content some (potassium, calcium magnesium) established study. Conclusion. For first time analyze plate used. stomatal apparatus, trichomes glands leaves studied are clarified. it found, that greater amount magnesium typical mínor, – hydropiper, potassium maculosa.
