From: Genetic mapping and physiological analysis of chlorophyll-deficient mutant in Brassica napus L
Phenotypic and chlorophyll fluorescence kinetics observations between the mutant type (Mut) and the wild type (WT) at the seedling stage. Note: A plants; B leaves. C to H show the fluorescence kinetics of Fo, Fm, Fv/Fm, ΦPSII, ETR, and Rfd, respectively. Top‚ WT; Bottom‚ Mut; Fo, initial fluorescence; Fm, maximum fluorescence; Fv/Fm, PSII maximum light energy conversion efficiency; Φ PSII, actual photochemical efficiency of PSII; ETR, apparent electron transfer efficiency; Rfd, fluorescence decay rate
