Fig. 4a–f.

PSI parameters in barley plants subjected to varying degrees of drought (a, c, e) and various CO₂ concentrations (b, d, f). a, c, e Open circles plants supplied with an external CO₂ concentration of 2,000 μl l⁻¹, closed circles 360 μl l⁻¹. b, d, f Open circles control plants, closed circles plants subjected to 0.15 M sorbitol, open squares 0.5 M sorbitol. Means ± SE of at least 4 replicates
