Environmental and genetic control over blackwood (Acacia melanoxylon) timber colour, density, and recovery. The project will investigate the roles of environment and genetics in the expression of wood characteristics in blackwood. It will determine the potential heritability of valuable blackwood wood traits and provide a sound understanding of the basis of colour expression. Heartwood characteristics, particularly colour, density, ring width and knottiness determine the commercial value of blac ....Environmental and genetic control over blackwood (Acacia melanoxylon) timber colour, density, and recovery. The project will investigate the roles of environment and genetics in the expression of wood characteristics in blackwood. It will determine the potential heritability of valuable blackwood wood traits and provide a sound understanding of the basis of colour expression. Heartwood characteristics, particularly colour, density, ring width and knottiness determine the commercial value of blackwood. The limited research on these characteristics, all undertaken outside Australia, points to combined genetic and environmental control. By understanding the relative importance that environmental conditions and genetic material have in producing desirable wood traits, growers will be better able to realise the full commercial value of blackwood.Read moreRead less
Selection and deployment of browsing resistant Eucalyptus globulus and Eucalyptus nitens. Marsupial browsing is a significant problem for eucalypt plantation establishment in Australia. To date, browsing control has relied on the use of 1080 pesticide, but through political and social pressure this will cease in Tasmanian State Forests by December 2005. To develop new approaches to integrated pest management, we will explore the use of natural plant resistance to marsupial browsers. We will dete ....Selection and deployment of browsing resistant Eucalyptus globulus and Eucalyptus nitens. Marsupial browsing is a significant problem for eucalypt plantation establishment in Australia. To date, browsing control has relied on the use of 1080 pesticide, but through political and social pressure this will cease in Tasmanian State Forests by December 2005. To develop new approaches to integrated pest management, we will explore the use of natural plant resistance to marsupial browsers. We will determine the genetic and chemical basis of seedling resistance in Eucalyptus globulus and E. nitens, and investigate the stability of resistance though tree development and across different sites. Resistant germplasm will be identified and tested in operational plantings.Read moreRead less
Ultra-high-throughput genotyping of Eucalyptus trees: Development and application of diversity array technology for genomic studies. A major international eucalypt genomic project is underway. Australia needs to take part because the Australian public would expect Australia to be at the forefront of research on one of its national symbols. Eucalypts are critically important to biodiversity and commercial forestry. The development of the proposed generic eucalypt DArT chip will help keep Australi ....Ultra-high-throughput genotyping of Eucalyptus trees: Development and application of diversity array technology for genomic studies. A major international eucalypt genomic project is underway. Australia needs to take part because the Australian public would expect Australia to be at the forefront of research on one of its national symbols. Eucalypts are critically important to biodiversity and commercial forestry. The development of the proposed generic eucalypt DArT chip will help keep Australia at the forefront of genetic and genomic research in eucalypts and help develop our biotechnology industry. Such research is essential for future forest tree breeding. Furthermore, eucalypt forests are one of our most important natural assets and their continual preservation requires that we develop better knowledge of their natural genetic variation and development.Read moreRead less
