Many Australian plants produce poor quality seeds or seeds that are deeply dormant. Successful plant establishment by cuttings can often be difficult and sometimes impossible. Research into new propagation technology is essential for meeting the present and future demands for the efficient mass propagation of Australian plants to be used in land restoration and for horticultural utilisation. Somatic embryogenesis has a high potential as a clonal propagation method and it has been estimated that 60,000 plants can be obtained from one gram of parent tissue. The aim of this study is to deliver a superior, mass propagation method for native plant taxa that cannot normally be produced by conventional techniques. This study undertakes a detailed examination of the effects of various factors including plant growth regulators and media nutrients on somatic embryogenesis for several species important for the horticultural and rehabilitation industries.
