Biotechnology was viewed as being necessary to increase reproductive cycles of the trees and to improve tree stock. The Ponderosa Pine, the Siberian Elm and the Silver Maple were those trees studied for improvements. Western Gail Rust infects 13 species of hard pines in North Dakota. Plant tissue culture, co-culturing techniques and recombinant DNA technologies were being applied to these 3 aforementioned tree selections.North Dakota State UniversityApplications of Biotechnology to Shelterbelt ImprovementArticle
