Biomorhological peculiarities of the supralittoral vascular plants of Primorsk region

Supralitoral is intermediate, or boundary, the zone between the land and the sea. Conditions of growing plants in a supralitoral zone were close to the extreme. They were aggravated with an anthro-pogenous press on supralitoral which amplify dur-ing a rest season. Therefore plants develop special adaptations and form special vital forms (VF). The studying of flora of a supralitoral of Primorye al-lowed estimating from new positions the biodiversi-ty of the South of the Far East on the example of specific coastal and sea group of plants. Despite numerous researches of sea coasts of the Far East of Russia biomorphological features of flora of su-pralitoral of Primorye were studied insufficiently. The research objective was to allocate and analyze vital forms of typical supralitoral species of vascular plants of Primorsk Region. 48 samples of 9 species of the grassy coastal and sea plants which were stored in the Herbarium of the Botanical garden institute (Vladivostok) were studied. They were brought together by employees Far East Biology and Soil Institute of Russian Academy of Sciences and Far East Botanical Garden Institute of Russian Academy of Sciences in Hasansky, Lazovsky, Ter-neysky Areas of Primorye and, including, in the territory of the Sikhote-Alinsky biospheric reserve. In supralitoral flora of Primorsky Region 25 species of vascular plants of 21 VF types are known. It was established that most of all typically supralitoral types (5) included Chenopodiaceae family, on 3 varieties. Asteraceae and Cyperaceae families. Rhoda Carex and Atriplex contained 3 varieties, the others had 1 variety. For 9 typically supralitoral types biomorphological descriptions were made and vital forms were allocated. It was shown that from 10 VF types 3 types of polycarpic herbs pre-vailed: extended tapped, long-rooted, extended and long-rooted rosellate. Three main models of shoot formation were allocated: rosellate, semirosellate and extended among which extended model pre-vailed.
