Краткое описание

The peculiarities of growth and development of water fern Salvinia natans (L.) All., the surface microstructure of vegetative and reproductive organs was studied using the scanning electron microscopy. Its existence at the water and air interface is ensured by the specific microstructure of floating fronds. Abaxial surface of floating and submerged fronds has thin cell walls of the epidermis and numerous filamentary outgrowths in epidermal cells. Sporocarp membrane structure contributes to the annual summer-green phenorhythm, promotes mega-and microsporangia submerging to the bottom in autumn and their rising to the water surface in spring.
