- Аннотация: MERTENSIA MARITIMA (L.) S.F. GRAY OF THE WHITE SEA LITTORALS: MORPHOLOGICAL, BIOLOGICAL AND ANATOMICAL ASPECTS OF ADAPTATION TO THE ENVIRONMENT. M. maritima is a supralittoral halophytic rhizomatous herb with peculiar leaves. Its foliage leaves were revealed to be epetiolate, but their leaf blades are differentiated into distal plane laminate part and proximal seemingly narrow one which has rolled margins and simulates the petiole. Specific adaptation of this species to the White See coastal environments were detected in its biology, morphology and anatomy. Amphistomatic leaf blade with dense stomata, dense venation and isolateral palisade tissue were concluded to be heliomorphic traits fitted to bright unsheltered sunlight. Thick epicuticular wax and partly rolled leaf blade were recognized to protect the leaf against dehydration caused by saline water, strong winds and high insolation. The species concerned was recognized to be a cryno-halophytic plant which excretes excess salt by glandular trichomes on the adaxial side of leaf blade. There is the mobile sand stony ground that was concluded to affect the growth pattern of the creeping rhizomes to make them intertwining and locally merging. Inter-rhizomatous grafting was described in M. maritima for the first time. Longitudinal splitting of the rhizomes and roots was revealed to result in vegetative propagation fitted to the mobile coastal substrates.
