Somatic embryogenesis of Pinus radiata has been seen as an attractive alternative to traditional propagation methods. This is due to its potential for high multiplication
rates and rejuvenation, as well as its compatibitity with molecular techniques. To date no commercial production of somatic embryos has been undertaken for direct planting, but field trials are currently being conducted for a combination of propagation methods utilising somatic embryos. The aims of this study were to provide a greater understanding of the factors that influence the initiation and maturation within the somatic embryogenesis process, in
order to further optimise conditions and efficiencies. Another objective was to analyse the technique's potential under Australian conditions, such as planting locations, genotypes and collection dates.
