Effects of AM inoculation and organic amendment, singly and in combination, on the growth and heavy metal uptake of tobacco grown in Pb/Cd contaminated soil
Tobacco plant is well-known for its capacity to concentrate heavy metals from its growing environment (Keller et al, 2003), and also, for example, can accumulate high levels of heavy metals particularly Cd in leaves and shoots (Lugon-Moulin et al, 2004). There have been numerous reports that cigarettes contained significant levels of various toxic metals, such as Cd, Pb, and As (Pappas et al, 2007; OConnor et al, 2010). Heavy metal uptake by tobacco plants mainly depends on the concentrations of these metals in the soil and their bioavailability, soil amendments (Adamu et al, 1989), and soil pH (Mulchi et al, 1987). Additionally, organic matter and soil microorganisms also influence metal bioavailability and hence metal content in tobacco. Many studies have shown that organic amendments of compost, farmyard manure and biosolid compost reduced the availability of heavy metal in soil due to high content of organic matter, P and Fe (Brown et al, 2003), showing a promising potential to decrease toxic metal content in tobacco plants(Lugon-Moulin et al, 2004).
