Tolerance to copper stress in Elephantgrass (Pennisetum purpureum) under soil culture
Elephantgrass (EG, Pennisetum purpureum Schumach),is a high biomass yielding gramineous plant which originates from a tropical zone,and is commonly used as forage crop.Its nutritional value for animals has been well documented (Kabi et al.2005).Its potential biomass production is about 25 g m2 d‐1 and it has a potential biomass yield of 50‐60 Mg hm‐2 (20‐25 tons/acre) over long periods ( about 180d) with a linear growth rate ( Wang et al 2002 ).Recently, EG has been considered as an important bioenergy crop (Prine et al 2007).In order to evaluate and empolder EG as a bioenergy resource in regions that are polluted with heavy metals, such as farmlands nearby or in copper mine tail areas,it is necessary to understand the ability of EG to resist or tolerate copper stress.
