Towards the exploitation of the American hazelnut (Corylus americana)
… the theme of characterizing american hazelnut (Corylus american) germplasm for eastern filbert blight (EFB) resistance. EFB, caused by the fungus Anisogramma anomala, is a primary limitation to european hazelnut (Corylus avellana) cultivation in eastern North America. C. americana is the endemic …

Improvement of asexual propagation and Anisogramma anomala detection protocols to facilitate applied breeding of new Corylus avellana and C. americana x C. avellana germplasm
Though hazelnut (Corylus L.) breeding has a long history, the discipline is still in the early stages of its development. Global hazelnut production continues to rely on wild selections and local cultivars in many countries. The lack of new cultivar development is a consequence of underutilization …

Influence of climate changes on cross allergies: possible involvement of pollen transglutaminase
… species of pollen, an aero allergenic (hazelnut, Corylus avellana) pollen, whose allergenicity is well documented, and an enthomophylus (apple, Malus domestica) pollen, which is not yet well characterized, to compare data on their mechanism of action in response to stressors. The two pollens have …

Late-quaternary environmental change at Eastbourne, East Sussex
… The early Flandrian vegetation was dominated by Corylus and Pinus the latter genus being replaced by members of the 'Mixed-Oak Forest' before 8,770 plus or minus 50 B.P. Prior to this date, Juniperus expanded. The nature of the mid-Flandrian vegetation is unclear due to the presence of secondary …

Nitrogen Fertilization of Hybrid Hazelnuts in the Upper Midwest of the USA
Hybrids of Corylus avellana, C. americana and C. cornuta, are proposed as an alternative crop for the Upper Midwest. Current nitrogen (N) recommendations for European hazelnut production are based on research from Oregon and may not be applicable to hybrids in Minnesota due to differing soils, …

Habitat Selection By Female White-Tailed Deer in the Northern Black Hills, South Dakota and Wyoming
… aspen/beaked hazel/spiraea (Populus tremuloides/Corylus cornuta/Spiraea betulifolia), and pine/aspen habitats were avoided in winter. During spring, deer selected agricultural lands and aspen/beaked hazel/spiraea habitat, while all pine habitats were avoided or used in proportions equal to their …

Effects of Soil Amendments and Biostimulants on the Post-transplant Growth of Landscape Trees
… medium, high) on the growth of container-grown Corylus colurna L. (Turkish hazelnut) seedlings. Biostimulants did not increase top growth compared to control treatments, but root growth was increased by granular humate at a medium fertilizer rate. The second experiment examined the effects of …
