中文摘要	类芦(Neyraudia reynaudiana)是一种具有极强耐干旱,贫瘠,高温等逆境的多年生禾草植物,是南方水蚀荒漠化地区,采矿采石厂及各类边坡植被自然恢复中的先锋植物.为探索在各类矿区及受重金属污染的地区采用类芦进行生态修复的可行性,通过室内发芽试验,对类芦种子在Hg2+, Cr6+, Cd2+, Pb2+, Zn2+, Cu2+等6种重金属离子胁迫及不同pH值条件下的萌发能力进行了研究.结果表明,类芦种子在pH值为5.09.0的范围内具有良好的萌发能力;6种重金属离子随着处理浓度的升高,对类芦种子的抑制作用逐渐加强,且出现显著抑制作用的最低浓度顺序为: Cd2+
英文摘要	Burma reed(Neyraudia reynaudiana)is a perennial grass which has the capacity of strong tolerance to drought, leanness, high temperature, and acid. It is a pioneer plant in natural vegetation restoration in the deserted area resulted from water erosion, mining area, stone pit, and slope. In order to explore the feasibility of ecological restoration with burma reed in various mining areas and the heavy metal contaminated area, germination ability of burma reed seed stressed by different concentrations of Hg2+, Cr6+, Cd2+, Pb2+, Zn2+, and Cu2+,as well as different pH values was studied by lab germination test. Results showed that burma reed seed can well germinate between pH 5.09.0. Inhibiting effect of the heavy metals on burma reed seeds increased with increase of heavy metal concentration. The order of the heavy metals,by the lowest concentration which leaded to inhibition, was Cd2+
