Bolondinskiy V. K. Research of dependence of photosynthesis on the intensity of solar radiation, air temperature and humidity in karelian (curly) and silver birch plants // Transactions of Karelian Research Centre of Russian Academy of Science. No 2. Experimental biology. 2010. Pp. 3-9
Keywords: Betula L.; Karelian birch; gaseous СО2 exchange; optimum of photosynthesis
The effect of light exposure, air temperature and humidity on photosynthesis in Karelian birch (Betula pendula var. сarelica) and silver birch (B. pendula var. pendula) was studied under natural conditions. The zones of light and temperature optima of photosynthesis, as well as the combination of light and temperature factors supporting maximal rates of photosynthesis were found by mathematical modeling. It was shown that in the situation of atmospheric drought, СО2 absorption by Karelian birch was lower than by silver birch. The patterns detected can be viewed as a first step to finding the ecophysiological characteristics of the species in question.
