TL;DR: An improved method for accelerated production of large quantities of Scots pine for clonal tests is described and mature somatic embryos accumulated amounts of storage proteins that were similar to the amounts in mature zygotic embryos.

TL;DR: The number of mature somatic embryos produced per gram fresh weight of embryonal mass was significantly affected by the three factors tested: embryogenic line, sucrose concentration, and abscisic acid concentration.

TL;DR: Regeneration of plants by somatic embryogenesis (SE) was achieved in Stone pine (Pinus pinea), one of the most characteristic tree species of the Mediterranean ecosystem, and Proliferation of embryonal masses (EM) was significantly improved when they were subcultured after dispersing in liquid medium and collected on filter paper disks, instead of being subculturing as small clumps.

TL;DR: Zygotic embryos from open-pollinated seeds of 20 black spruce families were used to investigate the proportion of genotypes that would give rise to embryogenic tissue (ET) and mature somatic embryos, indicating the additive nature of the genetic variation.

TL;DR: Progress in defining the physical and chemical factors that help the conifer cuttings and microshoots to develop adventitious roots are focused on, which include plant growth regulators, carbohydrates, light quality, temperature and rooting substrates/media as major variables for development of reliable adventitious rooting protocols for different conifer species.
