Progress is reported in research to increase biomass yields from coppice forests by admixing the nitrogen fixing tree Alnus glutinosa to plantations of Plantanus occidentalis and Liquidambar styraciflua. Plantations to compare growth rates of pure and mixed plots of the three species have been established on two sites in Georgia. Locations were selected on the basis of physiographic province (Piedmont and Coastal Plain) on soils which probably will be available for short rotation forestry. Propagation techniques for mass-cloning Platanus occidentalis using single buds and internodes of dormant or active twigs from young trees were developed. Tissue culture procedures were used to induce bud and root formation in callus cultures of Robinia and Gleditsia. Research dealing with fluctuations in starch and sugar levels in coppiced root systems of sycamore during the winter is reported. Total available carbohydrates ranged from 15 to 26 percent of root dry weight and starch to sugar conversion was detected. However, more starch disappeared than could be accounted for by the concomitant rise of sugar levels. There were some differences between annually coppiced root systems and those cut every two years.
