Track 2-9-1: Alternative Use of Grasslands for Medicinal Plants, Biofuel and Wildlife Products
Description
In Mediterranean regions, the development of a bioenergy sector is restricted by the scarce availability of species and varieties suitable to cultivation in rainfed environments, where summer drought affects plant survival (Scordia et al., 2014). Native perennial grasses that survive summer drought in a dormant or semi-dormant state may represent potential bioenergy crops. Nevertheless, the native germplasm of Mediterranean perennial grasses is unexplored for bioenergy production, except for giant reed, and little investigated also for other uses, as forage production. Smilo grass (Piptatherum miliaceum (L.) Coss) is a native species growing in marginal environments and it is palatable up to flowering stage. Its high aboveground biomass production suggests the alternative use as bioenergy plant when its palatability decreases. The aim of this study was to evaluate the degree of variability in dry matter yield, biomass partitioning among organs and feedstock quality for bioenergy uses in Sardinian native smilo grass populations.
