background persian oak (quercus brantii) belongs to the fagaceae family. it is a medicinal plant which is commonly used by the tribes in south western iran to treat inflammatory and gastric ulcers. objectives the aim of this study was to evaluate the effectiveness of persian oak ointment on dermal wound healing in rats. materials and methods for making full-thickness wounds in rats, the excisio...

acorn production plays a fundamental role in the organization and dynamics of oak forest ecosystems. regarding acorn importance, visual survey methods have been used to estimate acorn production of oak species throughout the world. in this study, the mast indices of brant`s oak (quercus brantii lindl.) were determined in a section of northern zagros forests, almost 36 ha area, near baneh, kurdi...

objective(s): the aim of the present study was to evaluate the effect of quercus brantii galls extract on the rat skin burn wound healing. materials and methods: ethanol extract of the galls of q. brantii was used to treat the induced burn wounds on the back of 32 wistar rats divided into 4 groups. the groups were treated by placebo, 1%, 2% and 4% concentration gall extract gels for 14 days and...

In Korea, mass mortality of Quercus mongolica trees has become obvious since 2004. Raffaelea quercus-mongolicae is believed to be a causal fungus contributing the mortality. To evaluate the pathogenicity of the fungus to the trees, the fungus was multiple- and single-inoculated to the seedlings and twigs of the mature trees, respectively. In both the inoculations, the fungus was reisolated from...

We developed the densest single-nucleotide polymorphism (SNP)-based linkage genetic map to date for the genus Quercus An 8k gene-based SNP array was used to genotype more than 1,000 full-sibs from two intraspecific and two interspecific full-sib families of Quercus petraea and Quercus robur A high degree of collinearity was observed between the eight parental maps of the two species. A composit...

Oaks provide a model system to study maintenance of species identity by divergent selection since they maintain morphological differences and ecological adaptations despite interspecific hybridization. The genome of closely related interfertile oak species was shown to be largely homogeneous, with a few genomic areas exhibiting high interspecific differentiation possibly as result of strong div...

Forest communities change in response to shifting climate, changing land use, and species introductions, as well as the interactions of established species. We surveyed the oak (Quercus L. spp.) community and Acorn Woodpecker (Melanerpes formicivorus (Swainson, 1827)) population within 230 ha of oak forest and savanna in central coastal California in 1979 and 2013 to assess demographic changes ...
