Description	The pigment composition and photosynthetic activity of sun and shade leaves of deciduous (Acer, Fagus, Tilia) and coniferous (Abies) trees was determined by studying the photosynthetic rates and by imaging the Chl fluorescence decrease ratio (RFd). The thicker sun leaves and needles had a lower specific leaf area, lower water content, higher total chlorophyll (Chl) a+b and total carotenoid (Cars) content per leaf area unit, as well as higher values for the ratio Chl a/b compared to the much thinner shade leaves that possess a higher Chl a+b and Cars content on a dry matter basis and higher values for the weight ratio Chls/Cars. Sun leaves and needles exhibited higher rates of maximum CO2 assimilation (PNmax) measured at saturating irradiance associated with higher maximum stomatal conductance. The differences in photosynthetic activity between sun and shade leaves were sensed via imaging RFd, since it linearly correlated to the PNmax rates at saturating irradiance.
