- Among the large diversity of plant species in Australia are many which produce potentially the longest-living seeds in the world. Many others have much shorter storage potentials, which limits the usefulness of seed collections for germ-plasm conservation and breeding. Work at the NSW Seedbank is exploring the repro¬ductive fitness, germination and storage potential of many taxa of conservation and economic importance, including members of the Proteaceae family such as the Waratah (Telopea speciosissima) which is cultivated for its cut-flowers. Telopea speciosissima seed has limited long-term storage capacity as there was a general trend towards loss of viability in accessions stored at 5°C for 17 years or more. This paper presents an overview of this work with an emphasis on conservation and utilisation of genetic resources.
