为探讨马缨丹（Lantana camara L.）应用于植物修复的可行性，通过盆栽试验，研究了马缨丹对土壤中重金属镉（Cd）的耐性，以及不同施Cd水平下丛枝菌根真菌（Arbuscular Mycorrhizal Fungi，AMF）Glomus intraradices（GI）对马缨丹吸收和转运Cd的影响. 结果显示：当土壤Cd含量为50 mg/kg时，马缨丹的生长受到明显的抑制作用；当土壤Cd含量为10 mg/kg时，马缨丹地上部具有较高的Cd积累量. GI表现出对Cd较强的耐性，能较好地侵染马缨丹根系. 与对照相比，接种GI能缓解Cd对马缨丹的生物毒性效应，显著提高马缨丹的生物量（P＜0.05）；接种GI对马缨丹转运Cd没有显著影响（P＞0.05），但当土壤Cd含量为100 mg/kg时,接种GI会抑制马缨丹对Cd的富集. 结果表明马缨丹对Cd具有较强的耐受性，在低Cd污染土壤中具有较高的提取效率；接种GI显著提高了马缨丹对Cd的耐性和地上部Cd的提取量（P＜0.05），表明马缨丹在修复Cd污染土壤方面具有应用潜力.
The pot experiments were conducted to investigate the tolerance of Lantana camara L. to cadmium (Cd), and the effects of arbuscular mycorrhizal fungus (AMF) Glomus intraradices (GI) on Cd uptake and translocation of L. camara growing in different Cd-added soils, aiming to explore the feasibility of phytoremediation technology using L. camara. The results showed that: the L. camara growth was inhibited significantly in 50 mg/kg Cd soil；L. camara had high Cd uptake in 10 mg/kg Cd soil. GI associated with L. camara well which was not influenced by Cd addition. Compared with the controls, GI symbiosis alleviated Cd phytotoxicity to L. camara, significantly and increased plant biomass (P＜0.05). The translocation of Cd was not significantly affected by GI colonization (P＞0.05). However, in 100 mg/kg Cd soil, GI inoculation reduced the enrichment of Cd in L. camara. The results indicated that L. camara showed high tolerance of Cd, and it had high extraction efficiency in slightly Cd-contaminated soil; GI inoculation significantly enhanced the tolerance and uptake of Cd in L. camara shoots (P＜0.05), showing the phytoremediation potential of L. camara for Cd-contaminated soil.
