TO IMPROVE EXISTING PRODUCTS AND DEVELOP NEW ONES Project Title: Development of North Queensland flower and foliage species and industry RIRDC Project No.: DAQ-299A Researcher: Ms Joanna Srhoj Organisation: Department of Primary Industries and Fisheries (Qld) Phone: (07) 4048 4651 Fax: (07) 4092 3593 Email: [email protected] Objectives • Commercial development of Stenocarpus sp. Tully River medium and fine forms (Forest Gem and Forest Lace respectively) and of Lomatia fraxinifolia, Athertonia diversifolia, Grevillea baileyana (leaf and stem production), Xanthostemon chrysantus, Sancotoecia serrata, Banksia plagiocarpa, Evodiella muelleri, Eucalyptus phoenicea and Neorites kevediana. • Increased industry size and capability. • Economic viability of species evaluated. Background These five native foliage species were selected for commercial development based on the results of a previous project – DAQ-262A. G. baileyana, L. fraxinifolia and A. diversifolia are all native to rainforests in north Queensland. S. ‘Forest Gem’ and S. ‘Forest Lace’ have been developed by Yuruga Nursery and are protected by Plant Breeders Rights. Research This research project has involved a number of different activities including: 3 field trials, post harvest research, test marketing, economic analysis and grower education. The field trials were used to test the impact of fertiliser and pruning treatments on plant health, survival, growth rates and yields. Post harvest trials have been used to test the vase life of A. diversifolia and L. fraxinifolia under a range of conditions. Tip maturity on S. ‘Forest Gem’ and S. ‘Forest Lace’ has been also assessed after a period of transport. Market research has been carried out in collaboration with wholesalers. Test samples of product have been sent for evaluations on a number of occasions throughout the project. Economic analysis has involved calculating gross margins for production of S. ‘Forest Gem’ and S. ‘Forest Lace’ grown under an intensive system of 8400 plants per hectare. Grower education and extension of project results has been a very important part of this project. Field walks, field days, meetings and information kits have all contributed to the extension of project results. Outcomes There have been a number of important outcomes from the research. Field trial results have revealed that S. ‘Forest Gem’ explants from hyko cells are not a viable option for industry. These plants took longer to establish and exhibited high losses when compared to the same species planted from forestry tubes. The growth rates and yield (1st year) have been determined for most species. All species were found to grow twice as fast during the summer months than in the winter months. Post harvest trials have revealed that Chrysal Professional 3 vase solution can extend the vase life of A. diversifolia leaves when compared to leaves tested in deionised water alone. Both A. diversifolia and L. fraxinifolia leaves exhibit satisfactory vase life under a range of conditions. Market research has provided indications of grower returns for the foliages. Information kits have been developed for existing and potential growers. WILDFLOWERS & NATIVE PLANTS 1 Research Report 2005 Implications • Bruising of A. diversifolia and L. fraxinifolia occurs easily during transport • S. ‘Forest Gem’ and S. ‘Forest Lace’ hyko explants are not recommended for industry Publications Information kits on the commercial production of each species.

'Best Bets' listing) for 'out of season' production during the key market
