  • Fluorescence parameters were calculated after 5 min of actinic illumination. Data are means of three (chlorophyll) to four\ (fluorescence parameters) biological replicates ± sd. Different superscript letters indicate significant differences from the wild type as determined by Fisher’s test (P < α = 0.05) from an analysis of variance. FW, fresh weight.
