Fig. 6From: Drought stress had a predominant effect over heat stress on three tomato cultivars subjected to combined stressTemperature response curve in the leaves of the three tomato cultivars under control, drought, heat and combined stress on day 4 and for the combined stress also on day 2. Different sub-graphs represent a, b, c net photosynthetic rate (P N), d, e, f stomatal conductance (g s), g, h, i transpiration rate (E) and j, k, l intracellular CO2 concentration (C i). The data represent mean values ± SE (n = 4)Back to article page
