Advances in the Maturation of Somatic Embryos of Pinus taeda and Pinus palustris

Somatic embryogenesis (SE) is a clonal propagation technique with the potential to capture the benefits of traditional breeding by realizing large-scale, clonal propagation of selected genotypes. Furthermore, it is a suitable tissue for genetic transformation. However, for most pine species, the percentage of SE initiation, subsequent conversion of immature embryos to mature embryos, and the production of viable seedlings, is still low, thereby reducing the applicability of this technique.
