Abstract: | The effect of different cadmium concentrations (6–120 μM) on Hill reaction activity (HRA) of isolated chloroplasts, contents
of chlorophylls (Chls) and carotenoids (Cars), and Cd uptake and accumulation in plant organs of Indian mustard (Brassica juncea L. cv. Vitasso) and mung bean Vigna radiata (L.) Wilczek] were determined. The Cd stress inhibited photochemical activity of isolated chloroplasts of both species and
in both tested developmental stages. On the basis of EC50 values, the mung bean showed a higher sensitivity to Cd treatment than Indian mustard. The higher sensitivity of both species
was determined in the earlier than in the older developmental stage. The leaves of Cd-treated plants possessed lower contents
of Chls and Cars in both species and the negative effect increased with Cd concentration. A difference between species was
also found in Cd uptake and accumulation. In both species, Cd was accumulated more in roots than in shoots, with higher accumulation
in Indian mustard than in mung bean. |
