Fig. 5From: Variation, coordination, and trade-offs between needle structures and photosynthetic-related traits across five Picea species: consequences on plant growthRelationships between the fraction of N allocated to different photosynthetic apparatus and Pnmax and PNUE. PC, PB, PL and Pphoto, the fraction of leaf N allocated to Rubisco, bioenergetics, the light-harvesting components and photosynthetic apparatus (%), respectively; Pnmax, area-based maximum net photosynthesis; PNUE, photosynthetic nitrogen use efficiency. Points represent trait values for each individual of each species. Explained variance (R2) and P values are shown. Solid lines in each panel represents significant linear regressionBack to article page
