Asexual embryogenesis and plant regeneration in Quercus Academic Article uri icon

abstract

  • Red oaks (Quercus rubra L.) were regenerated via direct and indirect asexual embryogenesis from immature zygotic embryo tissues. Late heart and early cotyledonary explants cultured in light on modified MS medium proved to be most embryogenic. Embryoids arose from explants cultured on various combinations of 2,4-D and BA. However, the highest percentages of normal polar embryoids were produced by explants cultured on growth-regulator-free media. Epicotyl dormancy of embryoids was overcome by desiccation (air drying and use of an osmoticum) and rehydration treatments. Asexual plantlet development paralleled developmental changes associated with seed germination. White oak (Quercus alba L.) embryoids were also regenerated, but failed to germinate. 1989 Kluwer Academic Publishers.
