Fig. 4: Effect of temperature on simulated cell radial length across the final ring under different model forcings in Pinus sylvestris L. growing at the same site as in Fig. 2, 1995.

a Simulated cell radial lengths at observed ("full model'') and observed +2 K ("full model +2 K'') temperatures with the full model. Also shown are results with the temperature increment of +2 K applied to only proliferating cells ("Prolif. +2 K''), or only enlargement-zone cells ("Enlarg. +2 K''). Each point is an individual cell at the end of the year and solid lines are mean cell-length profiles using a running mean over three adjacent 100 μm-wide bins. 100 radial files were simulated for each forcing. b Radial profiles of ratios of change in cell length to change in temperature using results in a), created by computing the difference in cell length profile from a full model run with observed temperatures from a run with an increase of +2 K each day applied to the full model, or the difference between a full model run at observed temperatures and a run with +2K applied to proliferating cells only ("Prolif.''), and the difference between a full model run at observed temperatures and one with a temperature effect on enlargement-zone cells only ("Enlarge.'').
