The aim of this study was to investigate the symbiotic relationship between arbuscular mycorrhizae () and the ability of rosemary () to mitigate urban traffic pollution. A factorial experiment with three replications and three factors (inoculated/non-inoculated with , traffic volume, and pot type) was conducted in Shiraz, a metropolis in south-central Iran. Inoculation with led to a 33% increase in root weight and a 20% increase in root length under a traffic volume of 4,200 Vehicles/H. Additionally, as traffic volume increased, stem length and dry weight of the entire plant inoculated with the fungus increased by 8.33% and 29.53%, respectively. The presence of fungus in the rosemary plant decreased the accumulation of Cd and increased the accumulation of Pb by 12.82% and 55.82%, respectively under traffic conditions of 4,200 Vehicles/H. The transfer factor (TF) of Cd and Pb in rosemary plant inoculated under these traffic conditions decreased by 25.74% and 25.24%, respectively. These findings indicate that mycorrhiza-inoculated rosemary plants can thrive in Cd- and Pb-contaminated soils, effectively remediating heavy metals, particularly Pb, with a TF >1.
本研究旨在探讨丛枝菌根（）与迷迭香（）缓解城市交通污染能力之间的共生关系。在伊朗中南部大都市设拉子，采用三因子三重复析因试验，三因子分别为（接种/未接种、交通量和盆类型）。在交通量为 4200 辆/小时的情况下，接种 可使根系重量增加 33%，根系长度增加 20%。此外，随着交通量的增加，接种真菌的整个植物的茎长和干重分别增加了 8.33%和 29.53%。在交通量为 4200 辆/小时的条件下，真菌的存在使迷迭香植物中 Cd 的积累减少了 12.82%，Pb 的积累增加了 55.82%。在这些交通条件下接种的迷迭香植物中 Cd 和 Pb 的转移因子（TF）分别减少了 25.74%和 25.24%。这些发现表明，接种丛枝菌根的迷迭香植物可以在 Cd 和 Pb 污染的土壤中茁壮成长，有效地修复重金属，特别是 Pb，TF>1。
