Fig. 3From: Variation, coordination, and trade-offs between needle structures and photosynthetic-related traits across five Picea species: consequences on plant growthRelationships between biochemical parameters and photosynthetic capacity across species. Pnmax, area-based maximum net photosynthesis; gs, stomatal conductance; iWUE, intrinsic water use efficiency; gm, mesophyll conductance to CO2; Vcmax and Jmax, maximum carboxylation and maximum electron transport rate, respectively. 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
