Evaluation, propagation, and tissue culture of hybrid white oaks (Quercus) for the urban environment

摘要

Asexual propagation of oaks has proven difficult for the majority of Quercus species using traditional methods of grafting or rooting cuttings, with the exception of Q. robur. In order to develop improved oaks, clonal propagation methods are requiredalong with an increased diversity of Quercus germplasm.Cornell's Urban Horticulture Institute (UHI] has been working towards addressing limitations in propagation and germplasm diversity through its long-term white oak breeding program. This program was initially developed between 2004-2006, when over 345 unique genotypes of hybrid white oaks were generated using 40-parent species from North America, Europe, and Asia.
