We tested this expectation by comparing the shell characteristics preferred by males and females in the shell-brooding cichl...

Hazelnut husk brown rot has been identified as a new disease in Liaoning Province recent years. The objective of this study to identify the pathogen. [Method] In study, standard sample hazelnut was collected from Songmudao Base Dalian City, Province. pathogen by studies morphology, pathogenicity, and analyses ITS LSU sequences. isolated purified, which confirmed Koch’s postulates. symptoms afte...

The objectives of this research were to investigate influences of energy inputs and energy forms on output levels and evaluation of CO2 emissions for hazelnut production in Guilan province of Iran. Moreover, the sensitivity analysis was done by marginal physical productivity (MPP) method for energy inputs and energy using linear regression. Initial data were collected from 120 orchar...

Hazelnut (Corylus avellana L.) is the one of the native and valuable shrub in Iran. Identification of the superior genotypes of hazelnut is the firs step for cultivation developing and breeding programs of this nut crop. In this research, had been studied phenological, morphological and pomological characters according to hazelnut’s descriptor for two years (2009-2010) on four populations of ha...

Plant microRNAs (miRNAs) are small and non-coding endogenous RNAs which have numerous regulatory roles in cells. These critical players regulate pathways either by inducing translational repression or messenger RNA (mRNA) decay. Newly developed bioinformatics tools and computational methods have been increased to identify miRNAs with their targets inside the genome. In this study, we predicted ...

kopet-dagh basin is located in north and northeast of iran. khangiran formation is one of the most important formations of paleogene deposits. for study of khangiran formation bivalves, chehelkaman syncline section has been selected. this section located in west of sarakhs city, east of kopet-dagh basin. lithology of this formation in the sarakhs region composed of marl, marly limestone and sil...

The high efficiency of monocoque cylindrical shells in carrying axial loads is curtailed by their extreme sensitivity to imperfections. For practical applications, this issue has been alleviated by introducing closely stiffened shells which, however, require expensive manufacturing. Here we present an alternative approach that provides a fundamentally different solution. We design symmetry-brea...

Hazelnuts are usually propagated by suckers or layering. However, other methods of propagation have been tested with variable results. Grafting is a method that has a few advantages such as fast multiplication rate, earlier fruiting and reducing sucker removal cost on specific rootstocks. Unfortunately, grafting is difficult due to slow formation of callus in hazelnuts. Here, we report the hypo...
