Fig. 4From: In situ chlorophyll fluorescence kinetics as a tool to quantify effects on photosynthesis in Euphorbia cyparissias by a parasitic infection of the rust fungus Uromyces pisi Normalized fluorescence induction transients (mean values of 5 measurements) from the leaf base and the leaf tip of infected Euphorbia plants, compared to healthy leaves. For double normalization the value at time 10 µs was set 0 and the value at 0.3 s to 1Back to article page
