Influence of cllimate warmening on flowering time of early and lately flowering forest plants

Abstract


It is popular to lean upon the bioclimatic models while discussing global warming influence on land and water ecosystems. These models to some extend assume similarity of phenological reaction of organisms on air temperature rising. In this connection the results of nine-year phenological observations of 22 forest plant species (trees, bushes, herbaceous perennial and annual plants) of broadleaved-coniferous zone in European part of Russia are considered. It is shown that species with early and late flowering demonstrate differently react on temperature rising in spring period. The reasons of unequal reaction of organisms on global warming are briefly discussed. As a whole the results of research confirm the assumption that species with early flowering most sharply react to climate warming.
