摘要：

Rates of whole chain and photosystem 2 activities in chloroplasts isolated from Vigna unguiculata L. seedlings grown under ultraviolet-B (UV-B) enhanced radiation were less affected by 3, 6 and 9 mM CdCl2 for 60 min at 0 degrees C in the dark than the rates in chloroplasts from control plants grown under normal irradiation. The results are in agreement with changes in contents of chloroplast 55, 47, 43, 33, 29, 27-25, 23 and 17 kDa polypeptides that were significantly lowered at 3, 6 and 9 mM CdCl2 only in chloroplasts from control plants. On the other hand, in the simultaneous treatment of chloroplast isolated from control plants the UV-B supported the inhibitory effect of all applied concentrations of CdCl2. The photosystem 1 activity was only marginally affected in the all experimental variants.
