In this paper, we explored the influence of Zn stress on plant growth, nutrient content and Zn accumulation in four varieties of ryegrass (Loliurn perenne L.) by pot experiment (root bag method). The results showed that Zn (at Zn concentrations of 0~520 mg/kg in soil) stimulated the plant growth of ryegrass, RTI (root tolerance index) was more than 1.0 (0~520 mg/kg Zn~(2 ) in soil). Zn stress (260 mg/kg or 520 mg/kg Zn~(2 ) in soil) did not inhibited N, P and K absorption by plant of ryegrass. The maximum or high Zn contents in shoots and roots were found at Zn treatments of 260 mg/kg or 520 mg/kg in soil, in which the maximium or high biomass were recorded. Zn contents in plant were increased with increasing Zn concentrations in soil. Zn contents and transport rates of Taide were higher than the other varieties of ryegrass (S/R>1). The maximums of Zn contents in shoots of Taide were found by 583.9 mg/kg DW (at Zn concentrations of 1 040 mg/kg in soil).
