MICROSTRUCTUAL FEATURES OF VEGETATIVE ORGANS OF ACONITUM NUSUTUM FISCH. EX REICHENB., AN ALKALOID-CONTAINING PLANT WIDESPREAD IN GEORGIA

Anatomical structure of the common in forests and meadows Georgian subalpine zone plant - Aconitum nasutum Fisch. ex Reichenb underground aerial vegetative organs, rich diterpene alkaloids, was studied. A set diagnostic features has been established using accepted microtechnical methods. The conductive system axial organs A. nasutum, root, twig leaf stalk, a separated collateral structure. Casparian strips are prominent root endoderma but no clearly expressed radial interaction with tissue is observed. thickening inner membrane differentiated vessels wood circular-spiral reticular. Basal cells epidermis arranged stitched, linear, thistle-rhombic underlying curved-walled type upper lower non-curved stitched. Both leaf-covering tissue, buds simple, anomocytic appearance. bifacial shape, dorso-ventral, hypostomatic structure, bundle conical shaped villi single-celled.
