CO2exchange in the leafy and skeletal parts of attached shoots of Pinus sylvestrisL. was measured with an infrared gas-analyzer in an open differential system during daylight hours. The 14CO2assimilation rates in the leafy parts of shoots and 14CO2evolution from current photosynthetic products in the lower skeletal part of shoots were measured in afternoons. Chlorophyll content was measured in the needles of the same shoot. The carbon of exported assimilates contributed only about 4% to… 
Chlorophyll Index and Photosynthetic Carbon Sequestration in Northern Eurasia Forests
An infrared gas analyzer was operated in an open-circuit differential mode to measure CO2 gas exchange in intact leafy and leafless parts of skeletal branches of Pinus sylvestris L. throughout the
Photosynthesis Limits Carbon Sequestering in the Taiga Zone of Northeastern Europe
The conclusion is that the primary photosynthetic productivity, which limits the production process, determines the dependence of the volume of the northern-taiga carbon reservoir on the latitude and climatic parameters.
Seasonal Signal of Photosynthesis in the Forests of North Eurasia
The seasonal course of the water potential in branch xylem reflects the dynamics of photosynthetic СО2/Н2О exchange in the forest stand. Long-term figures of water potential in the branches of major

Results of comparative analysis of turnover times and the capacity of major global pools of organic carbon are presented; the place of photosynthetic carbon sequestration is defined; concept of its
Decline in the Primary Productivity of Northwestern European Forests as a Consequence of Climate Aridization
Average annual age-dependent changes of carbon accumulation in the stemwood of major forest species (pine, spruce, and birch) of the taiga zone of the northwestern European Russia (Karelia) were

The Contribution of Lev Konstantinovich Kaipiainen (1937–2004) to the Studies of Plant Water Regime and Productivity
Lev Kaipiainen was born into a peasant family on August 20, 1937, in the village of Duderhof, Leningrad oblast. Through the 1940s, his family was several times deported, and it was only in 1949 that
