Figure 6. Confocal microscopy of NO changes (stained with DAF-DA and DAF-FM DA), lipid peroxidation (stained with BODIPY 581/591 C11) and general indicator of H₂O₂ (Amplex UltraRed) in root tips (upper panel) and upper part of roots (lower panel) of chamomile seedlings cultured on Petri dishes over 48 h with identical concentrations of Cd²⁺, PTIO and SNP as mentioned in Fig. 1.

Bar indicates 100 µm (A). Changes to content of Cd and phytochelatins (PC₂ and PC₃) in these seedlings (B). Total PC means that whole seedlings (shoot+root) were extracted.
