Values are percentages of total chlorophyll. Data presented as means ± SD (n = 3). Different lower case letters 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.
