A greenhouse experiment was conducted to investigate the effects of the arbuscular mycorrhizal fungus Funneliformis mosseae on three parameters: Pb, Zn, Cu and Cd accumulation, translocation and plant growth in perennial ryegrass (Lolium perenne), tall fescue (Festuca arundinacea), showy stonecrop (Hylotelephium spectabile) and Purple Heart (Tradescantia pallida). The purpose of this work is to enhance site-specific phytostabilization of lead/zinc mine tailings using native plant species. The results showed that mycorrhizal fungi inoculation significantly increased plant biomass of F. arundinacea, H. spectabile and T. pallida. The Pb, Zn, Cu and Cd concentrations in roots were higher than those in shoots both with and without mycorrhizae, with the exception of the Zn concentration in H. spectabile. Mycorrhizae generally increased metal concentrations in roots and decreased metal concentrations in shoots of L. perenne and F. arundinacea. In addition, it was found that the majority of the bioconcentration and translocation factors were lower than 1 and mycorrhizal fungi inoculation further reduced these values. These results suggest that appropriate plant species inoculated with mycorrhiza might be a potential approach to revegetating mine tailing sites and that H. spectabile is an appropriate plant for phytostabilization of Pb/Zn tailings in northern China due to its higher biomass production and lower metal accumulation in shoots.
进行了一项温室试验，以研究丛枝菌根真菌摩西管柄囊霉对多年生黑麦草（Lolium perenne）、高羊茅（Festuca arundinacea）、八宝景天（Hylotelephium spectabile）和紫叶鸭跖草（Tradescantia pallida）中铅、锌、铜和镉的积累、转运以及植物生长这三个参数的影响。这项工作的目的是利用本地植物物种增强铅/锌矿尾矿的特定地点植物稳定作用。结果表明，接种菌根真菌显著增加了高羊茅、八宝景天和紫叶鸭跖草的植物生物量。无论有无菌根，根中铅、锌、铜和镉的浓度均高于地上部分，但八宝景天中的锌浓度除外。菌根通常会增加多年生黑麦草和高羊茅根中的金属浓度，并降低地上部分的金属浓度。此外，发现大多数生物富集和转运系数均低于1，接种菌根真菌进一步降低了这些值。这些结果表明，接种菌根的合适植物物种可能是尾矿场地植被恢复的一种潜在方法，并且由于八宝景天具有较高的生物量产量和较低的地上部分金属积累量，它是中国北方铅/锌尾矿植物稳定作用的合适植物。
