Vegetative and tissue culture propagation technologies for use in genomics research and mass propagation systems for superior trees

Research is underway to develop protocols for in vitro selection, somatic embryogenesis, micropropagation, genetic transformation, and clonal propagation. These protocols are used to develop disease or pest resistance and induction or control of flowering in fine hardwood species. Species of interest include black walnut, black cherry, butternut, northern red oak, and green and white ash.

Success has already been achieved with several species in vitro and with rooted cutting propagation. These protocols are now being refined, results applied to other species, and plant materials are being acclimatized to the greenhouse and field environment.

This research will allow germ plasm improvement, which in turn will lead to improved hardwood tree characteristics. These improvements may include increased resistance or tolerance to disease, insects, and other environmental stressors.
