Description
Summary:Tissue culture systems offer many opportunities for the mass propagation and deployment of superior clones of forest trees. Somatic embryogenesis, micropropagation, and rejuvenation may all play a part. Micropropagation and the maintenance of juvenility, which were once greatly limited by genotype-specific responses in culture, are showing promise for clonal deployment via hedge production and rooted-stem cuttings. Rejuvenation systems using micropropagation techniques may also be possible. Somatic embryogenesis can provide a large-scale method for the mass production of thousands of somatic seedlings from superior clones, and it offers the potential for automated systems to produce large numbers of synthetic seeds. Limitations due to low initiation frequencies and the genetic specificity of explants are important problems. Establishment of field tests of somatic seedlings via somatic embryogenesis is now considered routine, and comparisons between somatic plants and zygotic seedlings are under way.
