Anatomical Structure of Polygonatum Mill. Species in the Precarpathian Region

Polygonatum Mill. species are found in woods of the temperate zone of the Northern Hemisphere. There are four species growing in Ukraine, the most common of which is Polygonatum multiflorum (L.) All. In forest and shrub habitats are also widespread Polygonatum odoratum (Mill.) Druce., Polygonatum latifolium Desf. and Polygonatum verticillаtum (L.) All. Polygonatum species have rhizomes of the sympodial type. They are of a primary anatomical structure. In the primary growth of the stem, as well as rhizomes, there is the central cylinder (stele) and the cortex. The structure of the leaf blade is related to the performance of basic functions: photosynthesis, respiration and transpiration. The leaves are isolateral with a lighter adaxial and shaded abaxial sides. The leaf is covered with epidermis. Beneath the epidermis is chlorenchyma, which makes up the leaf pulp - mesophyll. The microscopic structure of Polygonatum multiflorum (L.) All. was studied. The anatomic description includes the characteristic of rhizomes, leaves and stems structure.
