Fig. 3From: The photosynthetic and structural differences between leaves and siliques of Brassica napus exposed to potassium deficiencyImages obtained by imaging-PAM analysis of leaves and siliques in K-deficiency (−K) and sufficient K supply (+K) treatments. Values represent mean ± standard error (SE) of three replicates indicate the intensity of each parameter. F o: minimum fluorescence; F v/F m: maximum quantum yield of PSII; Y(II), actual photochemical efficiency of PSII; Y(NPQ), quantum yield of regulated energy dissipationBack to article page
