Cork Oak Trees (Quercus suber L.)
2006A transformation system for selected mature Quercus suber L. trees using Agrobacterium tumefaciens has been established. Embryos obtained from recurrent proliferating embryogenic masses are inoculated with AGL1 strain harbouring the plasmid pBINUbiGUSint, which carries the nptII and uidA genes.

Suberized Cell Walls of Cork from Cork Oak Differ from Other Species
Microscopy and Microanalysis, 2010AbstractPlants have suberized cells that act as protective interfaces with the environment or between different plant tissues. A lamellar structure of alternating dark and light bands has been found upon transmission electron microscopy (TEM) observation of cork cells and considered a typical feature of the suberized secondary wall.

STRATEGIES TO IMPROVE ROOTING AND ACCLIMATIZATION OF CORK OAK
Acta Horticulturae, 2003In this work the inclusion of 2 mg l -1 of indole-3-butyric acid (IBA) in the rooting medium produced 78% rooting. The rooting percentage was improved to 95% by basal immersion of shoots in 0.5 g l -1 IBA for 2 min. With this method high number of long and vigorous roots developed during the second week after IBA treatment.

The cork oak tree in California
Economic Botany, 1947There are 5,000 trees in various parts of the State, planted at various times, and recent experimental strippings of the largest have yielded 600 to 1,000 pounds of high quality cork per tree. Does this presage an American cork industry?

Modeling Cork Oak Production in Portugal
2006Cork oak (Quercus suber L.) stands are managed in agro-silvo-pasture systems and their sustainability depends on balanced relations amongst their components. Actual changes in management, mainly due to increasing mechanization and the installation of new stands, have required the development of tools to generate scenarios for management options.

Cork Oak Planting Tests in California
Journal of Forestry, 1949Abstract To study the possibilities of planting cork oak in the national forests of California, a number of plantations were established during a three year period beginning in 1942. From the results of these tests recommendations are made of how and where to plant for growing cork oak commercially.
