| 摘 要： | 近年来,土壤镉污染愈加严重,因此镉污染的生物修复也成为人们关注的热点之一。丛枝菌根是陆地生态系统分布广泛的植物-真菌共生体。研究证实,AM可促进植物的生长发育,增强植物对重金属毒害的耐性,影响植物对重金属的吸收、转运和积累,在重金属污染土壤的植物修复中显示出巨大的应用潜力。综述了AM对镉污染土壤修复的修复机理(直接作用、间接作用)及其在植物修复中的应用,并对未来的研究方向提出建议。 |

| Abstract: | As soil cadmium pollution has been more seriously in recent years,the bioremediation of cadmium pollution has received more concerns.Arbuscular mycorrhiza(AM) represents the most widely distributed mutualistic root-fungus symbiosis in terrestrial ecosystems.It’s been evidenced that AM can promote plant growth,enhance plant tolerance to heavy metals,influence uptake,transport and accumulation of heavy metals by plants,and thus indicating a huge potential for phytoremediation of heavy metal-polluted soil.The direct and indirect mechanisms underlying remediation of cadmium-polluted soil using AM and the application of AM in phytoremediation were reviewed and some future research directions in this field were suggested. |
| Keywords: | Arbuscular Mycorrhizal fungi cadmium pollution soil bioremediation |
