Abstracts |
A pot-culture experiment was carried out to investigate the effect of arbuscular mycorrhizal (AM) fungus (Glomus macrocarpum Tul. and Tul.) on plant growth and Cd2+ uptake by Apium graveolens L. in soil with different levels of Cd2+. Mycorrhizal (M) and non-mycorrhizal (NM) plants were grown in soil with 0, 5, 10, 40 and 80 Cd2+ mg kg(-1) soil. The infectivity of the fungus was not affected by the presence of Cd2+ in the soil. M plants showed better growth and less Cd2+ toxicity symptoms. Cd2+ root : shoot ratio was higher in M plants than in NM plants. These differences were more evident at highest Cd2+ level (80 mg kg(-1) soil). Chlorophyll a and chlorophyll b concentrations were significantly higher in AM-inoculated celery leaves. The dilution effect due to increased biomass, immobilization of Cd2+ in root and enhanced P-uptake in M plants may be related to attenuation of Cd2+ toxicity in celery. |
