Phytophthora cinnamomi is an important soil borne plant pathogen, associated to decline of cork and holm oak stands in Iberian Peninsula. This results from a complex biotic abiotic interactions culminating root infection. Field observations sites suggested enhancement moisture texture processes. Greenhouse assays were developed evaluate the impact on severity infection both species. Seedlings p...

Pollen analysis and AMS radiocarbon dating of a short sediment core from a mire in Veisar (Mazandaran province, N Iran) reveals the late-Holocene vegetation history of the area. High pollen values suggest that Caucasian alder (Alnus subcordata) has been present in the vicinity of the mire throughout the record. Wingnut (Pterocarya fraxinifolia), which was previously abundantly present, shows a ...

Oak and birch trees belong to Fagales order. Specific IgE to pollen allergens of both trees are frequently found in Korea pollinosis patients. Oak trees which comprise 40% of forest area are common in Korea. However, birch trees are sparse. We compared the allergenicity of pollen extracts of white oak, sawtooth and Mongolian oaks which are prevalent species in Korea, with the pollen extract of ...

Describing long-term dynamics in oak stands is hindered by a lack of archival data. In this study, archival data from the 1934 inventory of a 673ha area within the Sylamore Experimental Forest were compared to a recent 2002 inventory to quantify changes in forest structure and species composition of this upland oak forest in the Ozark Mountains of Arkansas. When established in 1934, the Sylamor...

During barrel maturation, the volatile compounds extracted from oak wood can contribute to a wine’s overall aroma and flavour, enhancing its character and complexity. However, barrels have a finite pool of extractable material and the amounts of oak derived volatile compounds available for extraction diminish over time. As a consequence, barrels are typically decommissioned after five to six ye...
