Figure 4.

Rosette area (total light-exposed leaf area per plant) of Italian and Swedish ecotypes of A. thaliana grown (A) under low light intensity (100 µmol photons m⁻²·s⁻¹) at a moderate leaf temperature (20 °C) and (B) at a hot leaf temperature (36 °C) under moderate light intensity (400 µmol photons m⁻²·s⁻¹). Mean values ± standard deviations (n = 3 to 4); significant differences (t-test) indicated by asterisks—** = p < 0.01. Data from Stewart et al. (A) [86] and (B) [76]. The latter references also include images of plants grown under the various conditions.
