Abstract The after‐effect of wind on photosynthesis and transpiration of Festuca arundinacea Schreb, was determined. Following a period of exposure In a controlled environment wind tunnel the wind‐treated plants showed reduced rates of photosynthesis when compared with the controls under standard conditions. Evaporation from paper model tillers was measured and the boundary layer resistance was shown to be low in all but very low wind speeds. Analysis of CO 2 and H 2 O diffusion pathways indicated that mesophyll resistance in wind‐treated plants was higher whilst leaf surface resistance was lower than in the controls. The high mesophyll resistance in the wind‐treated plants was attributed to reduced water content.
