Photosynthetic Active Pigments Changes in Norway Spruce (Picea abies) under the Different Acclimation Irradiation and Elevated CO2 Content
Figure 5
Specific leaf area (m2·kg−1) of Norway spruce needles. Legend on the right side represents acclimation irradiance 100 μmol·m−2·s−1 and 1200 μmol·m−2·s−1. AC—ambient concentration of CO2—350 μmol·mol−1, days 1−11 (elevated concentration of CO2: 700 μmol·mol−1).
