Most Japanese plum-type cultivars are self-incompatible and therefore cross pollination is necessary to ensure fruit set. Moreover, pollen can directly affect fruit development process and quality.  This study was carried out to investigate the effect of 6 pollen sources (‘Goje Sabz’, ‘Simka’, ‘Shablon’, ‘Methley’, ‘Myrobalan’ and ‘Black Star’) on  fruit quantitative and qualitative characteris...

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...

Several dwarf plum genotypes (Prunus salicina L.), due to deficiency of unknown gibberellin (GA) signalling, were identified. A cDNA encoding GA 2-oxidase (PslGA2ox), the major gibberellin catabolic enzyme in plants, was cloned and used to screen the GA-deficient hybrids. This resulted in the identification of a dwarf plum hybrid, designated as DGO24, that exhibits a markedly elevated PslGA2ox ...

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(1): 109–114. Due to the substantial damage caused in Hungarian plum orchards by the spread of plum pox virus (PPV), high-yielding, o en self-fertile German, Serbian and Romanian cultiv...

INTRODUCTION An experiment was conducted beginning in 2003 at a certified organic apple orchard in Iowa to evaluate insect pest and disease incidence in four scab– resistant apple cultivars (Delate et al., 2005). This on-farm experiment was resumed in 2007 after new grant funds were secured to compare pest loads with previous years’ results. The objective of the on-farm demonstration was to com...

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...
