Resumen: Phytochelatins (PCs)are known to detoxify heavy metals in plants. This study aimed to investigate the possibility of using PCs as a biomarker for chronic Cd toxicity in Silene vulgaris. For this purpose, the effects of Cd on growth rate, related to plant weight, and the PC concentrations were recorded throughout the bigger part of the vegetative phase. The lowest concentrations of Cd used, 1 and 2 M, inhibited plant growth rates by 30 and 50
