Abstract
The invention relates to a method for regeneration of plants of the genus Pinus by culturing explants of immature zygotic embryos on culture initiation medium containing abscisic acid, nutrients, growth hormones, sugar and a gelling agent to grow embryogenic tissue for cryopreservation. Culturing of the embryogenic tissue is continued on culture maintenance medium, embryo development medium, and germination medium. The germinated embryos are further converted to acclimatized plants for field planting. The method is well suited for producing clonal planting stock useful for reforestation.
