Summary:
Eastern cottonwoods (Populus deltoides) that are suitable for planting in Iowa that produce increased biomass have been developed at Iowa State University.

Development Stage:
The trees have been growing for several years and could be propogated 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.   Improved cottonwood (Populus deltoides) clones that produce increased biomass have been developed at Iowa State University.  These trees may facilitate the development of cottonwood plantations for biomass production in Iowa and similar climatic zones.

Group:
Advantage:
• The non-GMO cottonwood clone has increased woody density, improved winter hardiness, resistance to rust, and a high growth rate
Application:
Bioenergy; paper and pulp
