As part of the ongoing EC-Cost 87 Woody Plant Research Program, methods of establishing mature material of Quercus petraea (Mattuschka) Lieblein in culture were examined. Unopened buds taken from shoot tips were difficult to disinfect. Shoots produced from branch segments under mist established well in culture but increasing branch age and decreasing branch diameter reduced shoot production. Shoots produced from buds that had flushed inside transparent plastic bags, while still attached to the tree, established well in culture. Explants established in culture produced more shoots under light containing a high proportion of the red spectrum.
