Brief introduction of a bio-energy crop-Panicum virgatum;

Research progress on the clean bio-energy production from high yield Panicum virgatum;

Aboveground biomass and water use efficiency of an introduced grass,Panicum virgatum, in the semiarid loess hilly-gully region;

Dynamic research on relationship between switchgrass (Panicum virgatum) biomass and soil water in hilly region on loess plateau;

Three herbaceous grasses which were switchgrass(Panicum virgatum),Old World bluestem(Bothriochloa ischaemum) and foxtail millet(Setaria italica) seedlings were subjected to five different soil moisture treatments in growth chamber,which were high level(HW,80%FC,14.

Currently,many nations have sponsored the significant research effort to produce ethanol from switchgrass.
