Abstract
Comparative analysis of dark respiration was carried out for 18 plant species inhabiting arctic zone (Wrangel Island, lat. 71° N) and temperate zone (Leningrad oblast, lat. 59° N). For 15 pairs of species examined, the Stocker’s rule was proved valid; i.e., respiration rates of identical species were equal at average temperatures of their natural habitats. The concept of respiratory features in boreal and mountain plants is described in its historic development. The possible causes for controversial data are explained. It is concluded that gas exchange measurements in natural plant habitats are the only valid means for characterizing plant respiration. Only such measurements should provide the basis for the discussion of global climate changes.
