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 Plum pox virus (PPV), is considered to be particularly serious in stone species, has appeared research and documents since 1915 from which revelations emerge about the first symptoms appearing orchards central eastern Europe, where (PPV) being so viral, it caused production losses species such as plum, nectarine, cherry, almond, sour nectarine last but not least apricot, were 100%. creation...

Soluble solids concentration (SSC) is a reference index that typically used to quantify soluble sugars, the most abundant constituents of stone fruit flesh dry matter when approaching maturity. Dry (DMC) another parameter has been often associated with quality. This study investigated relationship SSC and DMC in fourteen cultivars at harvest. were measured physiological maturity peach, nectarin...

Trials were established at Aula Dei Experimental Station (EEAD-CSIC, Zaragoza, Spain) to assess graft compatibility between peach cultivars [Prunus persica (L.) Batsch] and new Prunus spp. rootstocks or selections. Peach cvs. Catherina and Tebana and nectarine cvs. Big Top and Summergrand were grafted on peach seedlings, plum rootstocks, almond x peach hybrids, and other interspecific rootstock...

Automatic in-field fruit recognition techniques can be used to estimate number, size, skin color, and yield in crops. Fruit color size represent two of the most important quality parameters stone ( Prunus sp.). This study aimed evaluate reliability a commercial mobile platform, sensors, artificial intelligence software system for fast estimates peach persica ), nectarine P. var. nucipersica plu...

Coniothyrium-like fungi are common wood and soil inhabitants and hyperparasites on other fungi. They belong to different fungal genera within the Pleosporales. Several isolates were obtained on wood of different Prunus species (plum, peach and nectarine) from South Africa, on Actinidia species from Italy and on Laurus nobilis from Turkey. Morphological and cultural characteristics as well as DN...
