Figure 3.

Variation in leaf traits of Arabidopsis thaliana plants under different growth regimes. Plants were grown in climate chambers under Low, Normal or High Light (LL, NL and HL; 30, 300 and 600 μmol quanta m^-2 s^-1, respectively) and under field conditions. A Leaf area (mm²), B length (mm), C width:length ratio, D width (n = 10). Different lower case letters above bars indicate significant differences (p < 0.001), according to separate Duncan's new multiple range tests followed by contrast analysis (indoor vs. field plants) applied to data presented in each column.
