Figure 12.14 Photosynthesis versus light response curves for seedlings of a shade-adapted rainforest tree species (Argyrodendron) and a sun-loving tree (Toona australis). Seedlings were grown under factorial combinations of weak, medium or strong light (shown left to right) × either high or low nutrient supply (solid lines with filled symbols, and dashed lines with open symbols respectively).
