Variation in chlorophyll in Arabidopsis thaliana leaves in 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 Total chlorophyll content and B Chl a/b ratio were determined from leaf discs (n = 3 pools of leaves each from 5-15 plants). 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.
