“…Various other techniques, e.g., the natural screening method of Harwood (1983) and artificial screening techniques of Eldridge et al (1983) and Hodge (1986), may be useful to avoid the unreliability of natural screening conditions. Through some or all of these options, frost resilience must be developed to realize the potential of Eucalyptus for applications such as short rotation woody crops in Florida (Dippon et al 1986). …”

Application. Clones of Eucalyptus grandis and E. grandis hybrids were naturally subjected to temperatures down to -6°C for 18 h in Florida. Locally adapted trees may be intensively screened to develop frost resilient candidates. Ortets must be further tested for vigor and frost resilience. Major commitments are needed to obtain satisfactory numbers of clones for operational use.Abstract. Eucalyptus grandis, E. grandis hybrid, and E. saligna hybrid trees, developed through as many as four generations of selection in southern Florida, were naturally exposed to exceptionally low winter temperatures. In a genetic base population and related field studies, 100 phenotypically superior cloning candidates were selected after an 8-h freeze with a low of -11 °C. Following propagation as rooted cuttings, 55 clones (typically 11-42 ramets per clone) were outplanted in a single-tree plot design and evaluated for 3.8 years which included two additional severe freezes. Significant clonal variation was observed in frost resilience, vigor, and quality. After composite evaluation for frost resilience, size, and form, only three clones were considered suitable for operational planting. Selection of further clones for outplanting requires major commitments to locate candidates and to test them. Field testing for frost resilience requires considerable investment, much beyond the requirements for developing fast-growing clones alone. Clones identified by testing will not be resistant to freezing conditions but will be resilient and greatly reduce the risks now associated with plantation culture in southern Florida.

“…SRWC systems maximize productivity for the above uses [11,[22][23][24][25][26][27][28][29][30][31]. Due to propagation ease, rapid growth, tolerance to high stand density, response to intensive culture, and coppicing, E. amplifolia can produce up to 67 green mt ha −1 yr −1 in multiple SRWC rotations as short as three years.…”

Eucalyptus amplifolia and Corymbia torelliana genetic improvement has been conducted in the lower southeastern USA by UF and collaborators since 1980. The collective accomplishments in genetic resources and potential commercial uses are summarized. For example, fast-growing, freeze-resilient E. amplifolia seeds are provided by 1st and 2nd generation seedling seed orchards (SSO) and a 2nd generation clonal seed orchard (CSO), while C. torelliana seed are available from 1st and 2nd generation SSOs. Breeding values (BV) have been developed for guiding the deployment of improved genotypes. Collaborative genetic improvement of these species is ongoing, including testing E. amplifolia in 11 countries and development of hybrid clones. Short Rotation Woody Crop (SRWC) systems may increase productivity and extend uses beyond conventional mulchwood to products such as medium density fiberboard (MDF), biochar, and energywood, while other possible applications include honey production, windbreaks, dendroremediation, and carbon sequestration. C. torelliana may be paired with E. grandis in two-row windbreaks to maximum windbreak effectiveness and may sequester as much carbon as E. grandis.

“…Short Rotation Woody Crop (SRWC) systems can maximize eucalypt productivity for such uses [8,23,25,30,33,[50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66]. Due to their easy propagation, rapid growth, tolerance to high stand density, response to intensive culture, and coppicing, E. grandis ( Figure 7) and E. amplifolia in SRWCs can produce up to 67 green mt ha −1 yr −1 in multiple rotations as short as three years in Florida.…”

Cooperative formed to provide additional support emphasized E. grandis, E. robusta, E. camaldulensis, and E. tereticornis and developed cultural practices for commercial plantations in southern Florida. In 1978, this cooperative united with the Hardwood Research Cooperative at North Carolina State University until 1985 when the 14-year effort ended after three severe freezes from 1983 to 1985. Eucalyptus planting and research were continued with a Florida-wide focus by the University of Florida and collaborators starting in 1980. The collective accomplishments in terms of genetic resources and commercial planting are summarized. For example, fast-growing, freeze-resilient E. grandis seedlings are produced by advanced generation seed orchards, five E. grandis cultivars are commercially available, as are E. amplifolia and Corymbia torelliana seeds. Genetic improvement of these and other species is ongoing due to beneficial collaborations. Short Rotation Woody Crop systems are promising for increasing productivity and extending uses beyond conventional pulpwood to applications such as windbreaks, dendroremediation, and energy wood.
