Significant linear positive dependence between CO2 assimilation and water vapour transpiration as well as negative dependence on water vapour concentration in the air for tested plant species was found. Positive inter-relation of CO2 assimilation and CO2 concentration in the air was recorded only at Plantago major L. Also positive dependence of assimilation on cobalt level in leaves of Plantago major L. In Taraxacum officinale Web was observed. Negative correlation of CO2 assimilation and iron and zinc contents in leaves was recorded. Photosynthetic system of Taraxacum officinale Web. is more susceptible to elevated concentration of these metals in leaves than Plantago major L.
