Photosynthetic Active Pigments Changes in Norway Spruce (Picea abies) under the Different Acclimation Irradiation and Elevated CO2 Content
Figure 4
Chl a/b content rate in 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, days 1−11 (elevated concentration of CO2: 700 μmol·mol−1).
