Leaf water potentials measured by in situ psychrometry were compared with leaf water potentials measured by the pressure chamber technique at various values of water potential in Helianthus annuus, Helianthus nuttallii, Vigna unguiculata, Nerium oleander, Pistacia vera, and Corylus avellana. In V. unguiculata, the leaf water potentials measured by the in situ psychrometer oscillated at the same...

Extraction of high quality RNA is a critical step in molecular genetics studies. Hazelnut is one of the most important nuts plants in the world. The presence of the taxol and other taxanes in hazelnut plant necessitates explaining their biosynthesis pathway and identifying the candidate genes. Therefore, an easy and practical method is necessary for RNA extraction from hazelnuts. Hazelnut has h...

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...

Aim of study: This study was conducted to classify hazelnut (Corylus avellana L.) varieties by using artificial neural network and discriminant analysis.
 Area Samsun Province, Turkey.
 Material methods: The physical, mechanical optical properties 11 were determined for three major axes. parameters included as independent variables, while dependent variables. Models created each the a...
