Clonal differences in biomass characteristics, coppice ability, and biomass prediction equations among four Populus clones grown in eastern North Dakota

Noted significant differences in biomass characteristics and biomass prediction equations in four hybrid poplar clones: "Siouxland', "Robusta', "Eugenei', and "Northwest'. There were differences in regression equation slopes among clones for leaf green weight, limb green weight, and leaf dry weight, differences related to the annual infection of "Northwest' by Melampsora leaf rust. All clones coppiced satisfactorily despite a late summer harvest. Clonal differences did exist in coppice ability and sprout growth vigor. -from Authors
