| 英文摘要 | Effects of application of zinc (Zn) (0, 1, 5, 10 mg kg(-1) soil) and phosphorus (P) (0, 10, 50, 100 mg kg(-1) soil) on growth and cadmium (Cd) accumulations in shoots and roots of winter wheat (Triticum aestivum L.) seedlings were investigated in a pot experiment. All soils were supplied with a constant concentration of Cd (6 mg kg(-1) soil). Phosphorus application resulted in a pronounced increase in shoot and root biomass. Effects of Zn on plant growth were not as marked as those of P. High Zn (10 mg kg(-1)) decreased the biomass of both shoots and roots; this result may be ascribed to Zn toxicity. Phosphor-us and Zn showed complicated interactions in uptake by plants within the ranges of P and Zn levels used. Cadmium in shoots decreased significantly with increasing Zn (P < 0.001) except at P addition of 10 mg kg(-1). In contrast, root Cd concentrations increased significantly except at Zn addition of 5 mg kg(-1) (P < 0.001). These results indicated that Zn might inhibit Cd translocation from roots to shoots. Cadmium concentrations increased in shoots (P < 0.001) but decreased in roots (P < 0.001) with increasing P supply. The interactions between Zn and P had a significant effect on Cd accumulation in both shoots (p = 0.002) and roots (P < 0.001). |
