In the mid-1960s, the first embryo-like structures were described, which were obtained from explants of the coniferous tree Thuja orientalis (Konar and Oberoi 1965;after Zenkteler 1984).…”

Somatic embryogenesis was studied in four spruce species (Picea abies, P. omorika, P. pungens Glauca and P. breweriana) to determine if this method can be used for in vitro propagation of coniferous trees. The highest frequency of initiation of embryogenic tissue was obtained when mature zygotic embryos were used as explants. It ranged then from 10.8% (P. breweriana) to 23.75% (P. omorika and P. pungens Glauca). The frequency of embryogenic tissue initiation was strongly affected by medium composition, i.e. addition of appropriate auxins (2,4-D, NAA, Picloram) and sucrose concentration (10-20 g·l -1 ). A lower frequency was obtained in Picea omorika (10%) when megagametophytes (endosperms with immature zygotic embryos) were used as explants. No embryogenic tissue was produced from hypocotyls, cotyledons and needles. A satisfactory frequency was achieved with the use of somatic embryos of Picea abies (30%). The proliferation of embryogenic cell lines of spruces was affected by medium type. The experiments resulted in production of somatic plantlets of P. abies and P. omorika. This enables the application of this method of spruce micropropagation for genetic and breeding research or for nursery production.

“…(Sasaki et al, 1988), Q petraea (Jörgensen, 1990), Q rubra (Gingas and Lineberger, 1989) and Q robur (Chalupa, 1990), somatic embryos were observed, but they are only of scientific interest, because they were induced on zygotic embryos, which means on genetically indefinite material. Only Feraud-Keller and Espagnac (1989) with Q ilex and Jörgensen (1988Jörgensen ( , 1990 with Q petraea could induce somatic embryogenesis with tissues of adult trees.…”
