Fig. 4. — Logarithmic plots of pigment parameters and PPFD_95%. Bold lines are linear regressions for the whole data (slopes all significant at P < 0·001); lighter full lines are regressions for mosses (open points), pecked lines are regressions for liverworts (filled points). (A) Chlorophyll (mg g⁻¹) and PPFD_95%; slopes of regressions for mosses and liverworts both P < 0·02, difference of slopes not significant. (B) Chlorophyll a : b and PPFD_95%; slope for mosses not significant, for liverworts P < 0·01, difference P < 0·05. (C) Quotient (total chlorophylls) : (total carotenoids) and PPFD_95%; slope for mosses P < 0·001, for liverworts P < 0·01, difference not significant. (D) Quotient (total chlorophylls) : (total carotenoids) and chlorophyll a : b; Slopes for mosses and liverworts both P < 0·01, difference P < 0·05.
