Summary:
Improved aspen clones that produce increased biomass have been developed at Iowa State University.

Development Stage:
The trees have been growing for several years and could be propagated by shoot or root cuttings

Description:
Fast growing trees such as aspen, cottonwood, and eucalyptus can be grown as so-called short rotation crops, and have potential to be used as a source of woody biomass for the production of biofuels such as wood pellets and cellulosic ethanol.  In the prime cottonwood growing region, which includes eastern Louisiana, eastern Arkansas, western Mississippi and western Kentucky, cottonwoods can grow 12-15 feet per year, allowing them to be harvested biennially.   In addition, cottonwoods will regrow from stumps, so that plantings may be managed through coppicing. However, cottonwoods in the Great Plains are susceptible to melampsora leaf rust, which reduces their vigor.  Aspens are also being targeted for development as a bioenenergy crop with the added advantage that they re-sprout from both the stumps and the roots.  Improved hybrid aspen clones that produce increased biomass have been developed at Iowa State University.  These trees may facilitate the development of aspen plantations for biomass production in Iowa and similar climatic zones.

Group:
Advantage:
• The non-GMO hybrid aspen clones have increased biomass production, good ability to re-sprout, and have the potential to be grown on marginal lands
Application:
Bioenergy; paper and pulp
