Abstract
AbstractThis paper reports on voltammetric methods applied in studies of transport processes connected with the occurrence of toxic cadmium in plants. As a means of transport across model of phospholipid membrane (PLM), calcium ionophore (calcimycin), cell‐penetrating peptides (transportan 10 and mastoparan), and finally protoplasts isolated from barley roots and leaves were used. Using calcimycin, different influences of Cd complexation by citric acid or by malic acid as examples of root exudates were documented. For transport of simplest phytochelatin PC2, voltammetric methods using formation of Hg complex on hanging mercury drop electrode (HMDE) or of Ag complex on mercury meniscus covered silver solid amalgam electrode (m‐AgSAE) were assessed.
