Differences in the fluorescence kinetics between sites of low and high nitrogen for Calamagrostis (sites b-3 versus b-2), Rhododendron (sites b-4 versus b-2) and Vaccinium (sites b-4 versus b-3) after double normalization between time 0 and 3 ms with linear time scale (K-band) (data of 13. September 2017)
