  • Patent number: 5731204
    Abstract: This invention relates to a method for regeneration of coniferous plants. In particular, this invention relates to an improved method for producing and developing somatic embroyos for somatic embryogenesis processes for plants of the genus Pinus and Pinus interspecies hybrids by including polyethylene glycol in the development media. This method is well suited for producing clonal planting stock useful for reforestation.
    Type: Grant
    Filed: December 20, 1996
