"The rate of photosynthesis, transpiration and effectiveness of water utilisation was studied in the wheat variety Mironovsk\u00A8\u02D8 in the years 2001 to 2002 in the greenhouse under controlled conditions. Plants were cultivated in four variants of the trial: control, drought, low soil pH and combination of drought and low soil pH. Physiological characteristics were measured gasometrically using the apparatus LCA \u00A8C 4 in the following developmental phases: 22.DC, 30.DC, 50.DC, 61.DC and 83. It is apparent from the results obtained that the rate of photosynthesis in all variants grew during ontogeny to phase 61.DC. The decrease of photosynthesis was recorded after this phase. Statistically significant decrease of photosynthesis appeared in the variant with combination of two stress factors compared with the control variant. The variant drought and low soil pH (DpH) reduced the rate of photosynthesis compared with the control by 45.26 %. Immediate rate of transpiration of wheat plants grew in both experimental"@en .
