Ecological and Anatomical Characteristics of riverbank Plants of Water Currents and Waterbodies of the Lower Amur Region

The results of an ecological and anatomical study of plants in the coastal shallows of rivers and lakes o the Lower Amur region are presented in order to identify their resistance and adaptability to the conditions of existence. 7 stenotopic species were studied. It was revealed that the vegetative organs of plants are characterized by a combination of typical hydromorphic and specific adaptive features. Adaptation of species to sandy-silty shallow habitats is carried out due to histological transformations of the main tissues. The narrow specialization of species does not affect the typical structure of plant organs and does not lead to a simplification of their internal structure. The studied species are more characterized by signs of terrestrial micromorphology (sclerification, suberinization and cutinization of tissues) rather than hydrophytic. It is assumed that a specific complex of shallow flora was formed mainly from terrestrial species.
