摘要:: 以狼尾草、大油芒和花叶芒为试材，采用盆栽法研究了低浓度（0.05 mmol?L-1）和高浓度（0.20 mmol?L-1）镉处理对3种观赏草生长、生理及金属离子吸收的影响，以期为城市特别是镉污染区观赏草的选择和利用提供参考依据。结果表明：2种浓度镉处理3种观赏草的生长高度和生物量均有不同程度的变化，花叶芒高浓度（0.20 mmol?L-1）处理与对照存在显著差异（P<0.05），大油芒生长高度对镉比较敏感，2种浓度与对照处理间都存在显著差异（P<0.05），而狼尾草的生长高度和生物量在镉处理下变化不大，与对照没有显著差异。2种浓度均可显著提高3种观赏草的游离脯氨酸含量和狼尾草抗坏血酸含量，但只有高浓度的镉处理能显著提高大油芒和花叶芒的抗坏血酸含量，低浓度则没有显著影响。高浓度镉处理3种观赏草可溶性蛋白质含量均显著降低（P<0.05），低浓度无显著影响。除了大油芒的丙二醛含量随着镉浓度增加而显著增加外（P<0.05），其它2种的丙二醛含量与对照没有显著差异。综合各项指标可知，3种草对镉的耐性表现为狼尾草>花叶芒>大油芒。此外，3种观赏草对镉均具有较强的累积能力，在2种浓度下，3种观赏草叶片中镉含量均显著增加（P<0.05）；2种浓度的镉胁迫下，3种观赏草对锌的吸收均低于对照，但高浓度的镉胁迫能够提高3种观赏草对铜的吸收。

Abstract:: Pennisetum alopecuroides,Spodiopogon sibiricus and Miscanthus sinensis were used as materials,potted cultivation method was used to study the variation of growth height,biomass,physiological indexes and the content of cadmium,copper and zinc of three ornamental grass,which were treated by two different concentrations of cadmium（0.05，0.20 mmol?L-1）.By these studies,the theoretical basis was provided for selecting the suitable ornamental grass for city afforest,especially in soil with cadmium pollution.The results showed that the growth height and biomass of three grass were changed with the cadmium stress,Miscanthus sinensis under the cadmium stress with high concentration had difference with CK (P<0.05).The growth height of Spodiopogon sibiricus was sensitive to cadmium stress which had difference with CK (P<0.05) under low or high concentration.The growth height and biomass of Pennisetum alopecuroides did not been changed and had no difference.The free proline content of three ornamental grass and the ascorbic acid content of alopecuroides that were induced by low or high concentration cadmium had difference with CK (P<0.05),and the ascorbic acid content of Miscanthus sinensis and Spodiopogon sibiricus was increased under the cadmium stress with high cadmium concentration.The soluble protein content of three ornamental grass did not been changed with low concentration cadmium,but was decreased with high concentration cadmium and had difference with CK(P<0.05).The malonaldehyde content of Spodiopogon sibiricus was increased with the increasing of the concentration of cadmium and had difference with CK(P<0.05),but other two grass did not been changed.In conclusion,the tolerance of three ornamental grass to cadmium stress was Pennisetum alopecuroides> Miscanthus sinensis> Spodiopogon sibiricus.In addition,three ornamental grass had better capacity to accumulate cadmium,the cadmium content of three ornamental grass was increased significantly under the cadmium stress with two different cadmium concentrations.In three ornamental grass,the zinc absorption level was lower than CK significantly under the cadmium stress with two different cadmium concentrations,and the copper absorption level of three ornamental grass was increased only under the cadmium stress with high cadmium concentration.
