This paper contains test results revealing norm and stress reactions of various life-form plants: trees — Betula pendula Roth, Tilia platyphyllos Scop., Pinus sylvetris L; water-plant -Galium palustre L.; grass — Solidago Canadensis; cereal — Secale cereal L. Collection and processing of the material was made in the area of Berlin/Brandenburg, Germany. Clark sensor-based method made it possible to determine the amount and rate of the oxygen evolution by plants in the dark and light phase. Under the reaction norm the average amount of the oxygen evolved and the average rate of metabolism processes during dark and light phases are changing simultaneously. Parabolic and periodic dependences of these changes during the vegetation period has been found. Under the stress reaction (drought, illness) the rate of metabolism dark reactions is increased by 2—3 times as compared with light reactions. The obtained results may be use for bioindication of the climate change in the Baltic Region.\u
