摘要:
Cyanide at levels of 50 to 100 μg NaCN/g soil was not only toxic to bush bean plants, but also resulted in increased uptake of Cu, Co, Ni, Al, Ti, and, to a slight extent, of Fe. Either the phytotoxicity from the cyanide or the metals resulted in increased transport of Na to leaves from roots. In studies with14C‐cyanide the transport of some cyanide into plants and to leaves simultaneously with the metals was demonstrated. There was a root, stem, leaf gradient for14C. From solutions, cyanide resulted in increased plant uptake somewhat of Cu, Zn, and Fe. The results have bearing on the use of cyanide as a metabolic inhibitor as well as on phytotoxicities of metals.
