Principal component analysis of heavy metal concentrations, bioconcentration factor (BCF) and translocation factor (TF) in examined samples (abbreviations see “Materials and methods”) in relation to photosynthesis activity parameters: net photosynthetic rate PN, stomatal conductance gs and intercellular CO2 concentration and (Ci), chlorophyll parameters and dry mass, relative water content (RWC) and cell membrane stability (MSI).
