In a greenhouse trials, the effects of arbuscular mycorrhizae fungi (AMF) on growth and uptake of N, P, K and Pb by Eucalyptus rostrata L., grown with or without Phaseolus vulgaris, in lead (Pb) contaminated soil were investigated. Inoculation of the host plants with AMF, Glomus deserticola spores, significantly increased the dry weight, shoot length, total N, P and K as well as chlorophyll con...

Arbuscular mycorrhizae (AM) are benefi cial symbionts for plant growth. They are associated with higher plants by a symbiotic association, and benefi t plants in uptake of phosphorus nutrients, production of growth hormones, increase of proteins, lipids and sugars levels, helps in heavy metal binding, salinity tolerance, disease resistance, and even in the uptake of radionuclides. Mycorrhizal g...
