ABSTRACT
Ontogenesis, life form, microstructure and age structure of coenopopulations of wide spread in East Europe species Cenolophium denudatum (Apiacea) on the north border of its area -- at the White Sea coast have been studied. C. denudatum are characterized as polycarpic with short or elongated rhizomes, with taproot and adventive roots and polyciclic semirosette shoots. The lability of roots and rhizomes is a principle means of adaptation to the special sandy biotops. At the White Sea coast coenopopulations of C. denudatum are normal, ontogenetic spectrum is left-hand, juvenile plants prevail; there are many temporarily not flowering generative individuals. The most reproductively active plants are found at the high sandy areas of the coast with stones and low concurention. The obtained results showed that at some associations of White Sea coast C. denudatum is not out of the zone of its ecological optimum. Refs 17. Figs 5. Tables 1.
