Figure 2 . Willow plantation (left) and poplar leaves (right)
Besides willow, also
hybrid poplar trees (
Populus sp.) are cultivated in SRC plantations as they have
similar fast-growing and high productive properties.Parallel to willow and poplar trees in Europe,
eucalyptus (
Eucalyptus sp.) plantations are grown in tropical regions.
Along with woody cellulosic energy crops also
perennial grass species are a promising opportunity
for future feedstock production. Miscanthus (
Miscanthus sinensis, M. sacchariflorus, Miscanthus x giganteus ), switchgrass (
Panicum virgatum) , and reed canary grass (
Phalaris arundinacea) are examples of
perennial crops that can be harvested every year. They have been the focus of considerable.
