Abstract

Miscanthus is a perennial grass, characterized by high yields. Yet, the cultivation of Miscanthus for bioenergy may generate land-use conflicts which might be avoided through the establishment of energy crops on marginal land. Moreover, in the Mediterranean region, water is a valuable resource and irrigation can represent a negative impact. In this context, this work aims to study the potentiality of Miscanthus (Miscanthus sinensis, Miscanthus floridulus and Miscanthus × giganteus) in Zn contaminated soils under a low irrigation regime. Results showed that biomass productivity of M. × giganteus, but not of M. sinensis and M. × floridulus were negatively affected by the contamination. M. × giganteus was the most productive genotype. Although the zinc removal percentages by Miscanthus accumulation represent 6% maximum, after three consecutive years, towards the Zn soil bioavailable fraction, the establishment of a Miscanthus cover represent an approach to attenuate and stabilize contaminated sites with additional revenue to owners.
