in recent years, symptoms of virus diseases on stone fruits have been observed in wide range in golestan province. in order to study the important viruses on stone fruits, cherry, plum, nectarine, peach and apricot trees with symptoms such as mosaic, chlorosis, ring spot, shot hole, pale margins in leaves and dwarf in trees, sampling was done during 2005. putative infected plants were tested by...

The recovery and conservation of traditional fruit tree cultivars is a necessity that faces a short window of opportunity due to accelerating cultivar erosion. Several efforts to preserve old material took place before the widespread use of molecular markers, but often that material has not been conserved in ex situ germplasm collections. Here we present a case in Spain where a thorough invento...

Electronic Product Catalogs (EPCs) are becoming more and more important as businesses interact electronically with one another and with customers. EPCs are the databases in which businesses store information about their products. EPCs allow customers to locate items they wish to purchase and business partners to access a business’s offerings. Typically each business’s EPC is organized to meet t...

Bud dormancy release is regulated by gibberellins (GAs). DELLA proteins are highly conserved and act as negative regulators in GA signaling pathway. The present study established a relationship between PmRGL2 in Japanese apricot and GA4 levels during dormancy release of floral buds. Overexpression of PmRGL2 in poplar delayed the onset of bud dormancy and resulted in dwarf plants, relative to wi...

The aim of this work was to follow Prunus necrotic ringspot virus (PNRSV) infection in apricot reproductive tissues and transmission of the virus to the next generation. For this, an analysis of viral distribution in apricot reproductive organs was carried out at different developmental stages. PNRSV was detected in reproductive tissues during gametogenesis. The virus was always present in the ...

This work aims to study the impact of solvent mixture (between 0 and 50% ethanol/water mixture) and temperature (between 25°C and 75°C) levels on the solid-liquid extraction of phenolic compounds (quantity and bioactivity) from apricot pomace. Results show that the mean augmentation of 1% ethanol in the range [0-12%] enhances by three times the extraction of polyphenols compared to the same aug...

Pectinase (Pectin methyl esterase) produced by Aspergillus niger in solid state fermentation of apple pomace using the optimized conditions was partially purified by (NH4)2SO4 fractionation (20-80% concentration). The purified enzyme was found to be stable up to 60 days. It remained heat stable up to 50oC but completely inactivated at 90oC. The partially purified enzyme showed highest activity ...

Increasing germplasm erosion requires the recovery and conservation of traditional cultivars before they disappear. Here we present a particular case in Spain where a thorough prospection of local fruit tree species was performed in the 1950s with detailed data of the origin of each genotype but, unfortunately, the accessions are no longer conserved in ex situ germplasm collections. However, fo...

Dried apricot is one of the stored fruit most endangered to be infested by the Indianmeal moth, Plodia interpunctella (Hübner). The aim of the present study was to identify volatile compounds from dried apricot that elicit an electrophysiological response in P. interpunctella adults. The volatiles were collected from the headspace of a glass vial with dried apricots using closed-loop-stripping ...

This article is divided into three parts. The first part, the most important one, deals with spectroscopic methods. Different regions of the electromagnetic spectrum are useful for fruit quality characterisation, in particular the visible and near-infrared regions. Concerning the visible one, studies have been carried out on apple, apricot, cherry, mango, peach, red table grape and tomato, when...
