“…2). In agreement with our results, Smilde et al (1992) concluded that Zn uptake by plants increased with applied Cd. Welch et al (1999) also found that uptake rates of Cd by roots of durum wheat (Triticum durum L.) increased as solution Zn concentrations increased.…”

The interactions of zinc (Zn) and cadmium (Cd) in uptake and translocation are common but not consistent. We hypothesized that Cd 2þ and Zn 2þ activity in the apoplasmic solution bathing root-cells could affect Zn accumulation in plants dependent on the wheat genotype. This hypothesis was tested using seedlings of two bread wheat genotypes (Triticum aestivum L. cvs. Rushan and Cross) and one durum wheat genotype (Triticum durum L. cv. Arya) with different Zn efficiencies grown in chelate-buffered nutrient solutions with three Zn 2þ (10 À11.11 , 10

“…The most commonly observed effect is an antagonistic interaction between Cd and Zn. [31][32][33] Increased supply of Zn in soil and hydroponic cultures has been reported to decrease Cd uptake by a variety of plant species including rice. [34] The effect is especially pronounced when Zn is raised from a deficiency to sufficiency level (rice, [23] lettuce [32] ).…”

Two solution studies were conducted a) to investigate the uptake of zinc (Zn) and cadmium (Cd) by rice plants (Oryza sativa L.) and interaction between these elements, and b) to determine experimental conditions for growing rice grain with desired Cd concentration for an animal feeding study. In both studies, free metal activities of cadmium and cationic microelements were buffered by an excess of chelating agents. The first study was a factorial design with two Zn levels (1.0 and 3.89 mM) and four Cd levels (0.81, 1.44, 2.56 and 4.55 mM) in the solution. In the second study, rice was grown in two solutions of different microand macro-element compositions and three Cd levels (0.0, 0.5, and 2.0 mM). In the first study, solution Zn concentration of 3.89 mM and corresponding free metal activity (pZn 2þ ) of 6.00 was toxic to young rice plants. With time, Zn concentrations in rice plants decreased while Cd concentrations increased. Toxic concentration of Cd in roots (about 100 mg kg À1 ) associated with

“…In T. caerulescens shoots, total concentration of Zn increased significantly in the combined treatment on moderately contaminated soil (Table 1) whereas no significant changes in Zn concentrations in total above-ground biomass could be observed for S. dasyclados. On the contrary, the Cd concentration in T. caerulescens tended to decrease, suggesting antagonistic pattern of Cd and Zn uptake (Smilde et al 1992).…”

Most phytoremediation technologies are based on the use of selected plant species cropped as in monoculture. Separated (monoculture) and combined (simultaneous) cropping of hyperaccumulator Thlaspi caerulescens and accumulator tree Salix dasyclados were tested in our experiment. We used moderately and highly contaminated soil. Extremely contaminated soil caused progressive mortality of willows planted separately. Combined cropping with T. caerulescens enabled willows to survive. Generally, we determined decreased bioaccumulation of As, Cd, and Pb in both tested species and Zn in willow plants. Combined cropping enhanced bioaccumulation of Zn in T. caerulescens shoots. The remediation efficiency of the individual species in the co-cropping system did not differ from those obtained in separate cropping mode. For As and Pb the negligible effectiveness of phytoextraction was confirmed for both separate and combined cropping of the tested plant species.
