Fig. 3From: Physiological, transcriptome and co-expression network analysis of chlorophyll-deficient mutants in flue-cured tobaccoDifferences in net photosynthesis and chlorophyll fluorescence parameters of tobacco leaves. (a) Net photosynthetic rate. (b) Y(II). (c) Fv/Fm. (d) Fv/Fo. Y(II), the actual photochemical efficiency of PSII (Y(II)); Fv/Fm, PSII maximum photochemical efficiency; Fv/Fo, and potential photochemical activity (Fv/Fo). Error bars indicate the standard error of the mean (n = 3 individuals per treatment group). Small letters indicate significant differences between treatments at p < 0.05, respectivelyBack to article page
