Abstract
The present invention provides methods for initiating embryogenic cultures of plants. The methods include the use of novel media compositions and elevated atmospheric pressure treatments to improve the frequency of embryogenic culture initiation. The methods are well suited for initiating embryogenic cultures in recalcitrant conifer varieties. The method is also well suited for producing somatic embryos that can be further cultured to produce large numbers of plants. Further, the invention provides novel methods that may be used to enhance somatic embryogenesis in a broad range of species.
