Relationship between net photosynthetic rate from steady-state light response (A_S) and electron transport rates from a rapid light response (ETR_R) for all tested materials at 100 (a,b) and 2000 (c,d) μmol m⁻² s⁻¹ PPFD. □ is Alnus formosana; △ is Salix Warburgii; ▽ is Ficus microcarpa; ▲ is Ardisia crenata; ▼ is Ardisia cornudentata; ○ is Pyrrosia lingus; ⊕ is Asplenium antiquum; ● is Diplazium donianum; ◆ is Archangiopteris somai. A_S for ferns and understory shrubs measured at 75% relative humidity were from [3]. *** is significant at p < 0.001.
