"Introduced study is oriented on change of energy balance in the photosynthesis measured on sugar beet by stressors as droughtness and extreme temperature.Besides that is concerned to some methodical questions, e.g. cause of the variability by daily biorythm, and by the onthogeny (means by oldness of assimilative apparatus). Is used the method of fast fluorescent analysis (FFI) and mathematical models. The results determined the impact of leave age (=made by sequence of leave in ground rosette from the border to centre made by growing peak) on Fo, Fm, rate of acquirement fluorescent maximum (Tfm), which determine energy balance, the activity of plastochinone, red/ox actions running in the photosynthesis and the yield of photosystem PSII. Extreme temperatures as also the droughtness affected significant change of FFI as changes of energy balance of photosystem PSII."@en . . "5"^^ . "[0A2467FD4179]" .
