Mycorrhizal formation in vascular plants of the White Sea western coast

The occurrence of hyphae, vesicles and arbuscules of the arbuscular fungi in the roots and root hairs of the dominant and co-dominant higher plants in the tidal zone of the western coast of the White Sea were investigated. Glaux maritima, Plantago maritima, Tripolium vulgare are characterized by the high frequency of arbuscular mycorrhiza. Puccinellia maritima is described as a type of species with low frequency of mycorriza. Salicornia europaea, Triglochin maritima are referred to the non-abruscular types of species. The growth of these plants in different flooding zones has no evident effect on the formation of mycorrhiza. The root hairs develop more actively in the non-arbuscular mycorrhizal species growing in the littoral tidal zone.
