The effect of mycorrhizal arbuscular fungus on phytoremediation potential of coriander, rosemary and ornamental cabbage in lead-contaminated soil

One of the ways to reduce soil pollution is the use of plants, which is more effective than other methods due to its simplicity, cheapness and compatibility with the environment. Mycorrhizal fungi symbiotic with plants can further reduce pollution by changing and modifying plant physiological processes.

In order to investigate the effect of arbuscular mycorrhizal fungus (Glomus muse species) on the phytoremediation potential of coriander, rosemary and ornamental cabbage in soils contaminated with lead, a completely randomized and factorial experiment with 3 types of plants (coriander, ornamental cabbage) And rosemary) had 6 levels of lead (0, 25, 50, 100, 200 and 400 mg of lead per kg of soil) and two levels of mycorrhizal arbuscular fungus (inoculation and non-inoculation) in 2017 in one of Abdanan greenhouses were done.

The results showed that with increasing soil lead levels, the concentration of lead in the roots and shoots of the plant increased. Arbuscular mycorrhiza increased the concentration of lead in the roots and shoots of rosemary. Mycorrhizal fungi also increased the concentration of lead in the aerial parts of ornamental cabbage but decreased the concentration of root lead. The highest concentration of shoot shoot was observed from rosemary plant and inoculated with mycorrhizal fungus and the lowest concentration of shoot shoot was observed from rosemary plant and not inoculated with mycorrhiza. The highest lead transfer factor was 5.8 from ornamental cabbage plant inoculated with mycorrhizal fungus and the lowest lead transfer factor was 0.7 from mycorrhizal plant inoculated with mycorrhiza.

The use of mycorrhizal arbuscular fungus increased the concentration of lead in the ornamental cabbage, which is used in phytoremediation of contaminated soils.
