Ecophysiological characteristics of plants as an element of biodiversity assessment at the intra- and interspecies levels
// Biodiversity of Fennoscandia (diversity, human impact, nature conservation). Petrozavodsk: Karelian Research Centre of RAS, 1997.
Assessment of the state of plant resources in natural and man-made cenoses is most often based on morpho-genetic criteria. Physiological indices are used much more rarely. However it is the physiological plasticity of an individual that greatly predetermines the possibility of its survival.

One of the integral indices of a genotype which reflects the eco-physiological characteristics is the interrelations between its CO-gas exchange and the major environmental factors. Modern experimental technology (artificial climate units, gasometric appliances, electronic recorders) allows to study gas exchange in plants with great precision. Due to the fact that environment is a multifactor system the study of quantitative relations between this system and plants is possible only on the basis of the systemic approach.

The multifactor method of simulating the interrelations between gas exchange in plants and environmental conditions in active designed experiments developed on the basis of the systemic approach (Kurets, Popov, 1991) allows to compute the absolute value of the potential gas exchange maximum and the conditions of its appearance, the limits of the optimum - the indices of the eco-physiological characteristics which reflect the peculiarities of interrelations between the genotype and the environment necessary to assess the biodiversity of plants both at the inter and intraspecies levels.
