self pollinated cultivars of hazelnut are limited mainly due to dichogamy and self- incompability. to enhance productivity of hazelnut orchards, identification and selection of suitable polinizers are necessary. to meet this quest, collection and evaluation of iranian hazelnut germplasm have began by department of horticulture research, seed and plant improvement institute, iran, since 1994. ha...

most of hazelnut orchards in iran have been established by planting native genotypes. to enhance productivity of these orchards, adapted and high yielding hazelnut cultivars are to be developed and released. to meet this quest, collection and evaluation of iranian hazelnut germplasm have began by horticultural crops research department, seed and plant improvement institute, iran, since 1994. ha...

Halyomorpha halys Stål, the brown marmorated stink bug (Hemiptera: Pentatomidae), is an invasive pest with established populations in Oregon. The generalist feeding habits of H. halys suggest it has the potential to be a pest of many specialty crops grown in Oregon, including hazelnuts, Corylus avellana L. The objectives of this study were to: 1) characterize the damage to developing hazelnut k...

Kernel size is the main hazelnut quality parameter for consumption market. However, industrial purposes are destination cultivars. This work aims to identify aptitude relationships kernel size, and qualitative nut traits eligible enhance hazelnut’s commercial value. The of cv “Negret” “Pauetet” were assessed via in-shell shelled sizes two years. In-shell hazelnuts tested weight, shape, percent ...

hazelnut (corylus avellna l.) is one of the important nut crops in world. the harvesting ofhazelnuts is done either by hand or by manual or mechanical raking of fallen nuts in iran.common hazel is widely cultivated for its nuts, including in commercial orchards in europe,turkey, and iran. there are some genotypes of hazelnut in iran that their growing areas arelimited to gillan, aredbil, mazand...

Iran has suitable conditions for cultivating high-quality varieties of hazelnuts (Corylus avellana L.). Most of hazelnut orchards in Iran have been established by planting native genotypes. Aspergillus flavus Link. (AF) is a filamentous fungus affecting hazelnut kernels in orchards and during storage conditions. The most widely explored strategy for reducing aflatoxin contamin...

Aim. Previous studies have shown a higher sensitization rate to hazelnut in processing workers but no relation was found between the respiratory symptoms in workplace and hazelnut sensitization. Material and Method. To evaluate the association between the hazelnut sensitization and workplace-related respiratory complaints, hazelnut processing workers had undergone a questionnaire included work-...
