Performance of eastern cottonwood and hybrid poplars on alluvial and upland sites in the southThis article is part of a larger document. View the larger document here.
Continued emphasis on woody biomass production under short rotation woody crop strategies has focused on both hybrid poplar and eastern cottonwood. The advantages of hybrid poplars in comparison to eastern cottonwood include superior rooting, better wood properties, and the ability to grow well on upland sites. Unfortunately, one specific disease, Septoria musiva, which results in stem canker and mortality, has shown to be the most serious impediment to the use of hybrid poplars in the Southern United States. Although disease still ranks as a significant problem in the Southern United States, a limited number of hybrid poplar clones have shown tolerance and changed the thinking about the use of hybrid poplars. In addition, a small population of eastern cottonwood clones has shown high survival and good growth on upland soils. New selections within parent populations may provide an even greater ability to develop more hybrid populations suited to the environment of the Southern United States.
