The effect of supplemental FR applied on a 3-cm-diameter spot of a leaf on parameters pertaining to between-leaf resource partitioning and within-leaf chloroplast organization. Six species were compared: Phaseolus vulgaris (Pv), Lysimachia vulgaris (Lv), Hedera helix (Hh), Ficus benjamina (Fb), Brachypodium pinnatum (Bp) and Carex acutiformis (Ca). Parameters (means ± s.e.) are: leaf mass per area (LMA), nitrogen per leaf mass (NLM), nitrogen per leaf area (NLA), photosynthetic capacity per area (Amax) and per chlorophyll (Amax/chl), total chlorophyll per area and chlorophyll a/b ratio. Differences between means were tested for significance with a t-test, for notation see legend to Fig. 1.
