Woody species for biomass production in Florida: Final report, 1983-1988
From 1983 to 1988, this project's short rotation woody crop research enhanced the potential of Eucalyptus species in Florida. A fourth-generation E. grandis seed orchard could produce over 100 million seedlings annually for use in southern Florida. Seed from the 50 best trees in the orchard may double the average productivity in the preceding genetic base population. Three frost-resilient and rapid-growing E. grandis clones are being commercially propagated by tissue culture, and over 250 additional clonal candidates are under test. While rooted cuttings of selected clones could be mass produced in less than seven months, micropropagation may reduce the cost of vegetative propagation. Eucalyptus tereticornis and E. camaldulensis demonstrated vigor and frost-hardiness and may be suitable for sandhills sites in central Florida and wetter sites further south. For northern Florida, E. amplifolia had good frost-resilience and remained vigorous through four coppice rotations. Coppicing of other eucalypts, notably E. grandis, is very dependent on climatic factors. Biomass properties of the eucalypts vary due to genetics and age but appear suitable for certain fermentation and pulping processes. Economic analyses suggest that E. grandis and E. amplifolia may be profitably grown and that short rotation culture appears feasible for slash pine, but cannot yet be advised for sand pine. 126 refs., 24 figs., 67 tabs.
