Інтенсивність фотосинтезу лучних рослин лівобережного лісостепу україни
Photosynthesis intensity of poic plants of left bank Ukraine’s Forest–steppe

Summary/Abstract: The intensity of photosynthesis is studied in species of 20 families of Magnoliophyta (Angiospermae). It is revealed that in general, dicotyledons have a higher rate in comparison with the monocotyledonous plant by 10.0 %. The average values with limits from 3.6 to 39.3 mg СО2/dm2 per year are given. The studied species are classified by the ability to assimilate СО2. The rate dependence on a biomorph and hygromorph is determined. It is stressed that rhizome species have sufficient and high values of that rate. The dynamics of values during ontogenesis and impact of weather conditions on them are shown.
