Figure 4From: Defence reactions in the apoplastic proteome of oilseed rape (Brassica napus var. napus) attenuate Verticillium longisporumgrowth but not disease symptomsQuantum yield of photosynthesis (A) and chlorophyll concentration (B) of oilseed rape ( Brassica napus var. napus ) after infection with Verticillium longisporum VL43. White symbols = non-infected plants, black symbols = VL43-infected plants. Data indicate means (n = 20 for quantum yield of PSII and n = 9 for chlorophyll, ± SE). * indicate significant differences between treated and non-treated plants at P ≤ 0.05.Back to article page
