the pomegranate seeds of four iranian commercial varieties  (abanmahi (ab), malas (ms), pust sefid (ps) and shahvar (sh)) were evaluated in terms of some quality properties including protein, oil, dietary fiber, mineral contents and fatty acid composition. physicochemical properties and antioxidant activity of pomegranate seed oils (psos) were also determined. the oil antioxidant activity was m...

salinity, as an abiotic stress, causes significant losses in horticultural production. future of grape production, as one of the most important economical horticultural fruits, depends on breeding programs and using salt tolerant rootstocks. the aim of this study was to investigate the salinity tolerance and the distribution of ions associated with salinity in six genotypes and varieties of gra...

vineyard management, plant nutrition, irrigation, genotype and pests and diseases are effective factors quantity and quality of crops. among mentioned factors, plant nutrition has more importance and nutrient imbalance in soil can affect crop quantity and quality. grape cluster necrosis at veraison time is important disorders in vineyard, because of lack of balance between potassium and magnesi...

frost in early spring is one of the limiting factors in the production of grape. chemicals offer useful approach to reduce low temperature-induced damages. different concentrations of salicylic acid including: 0 (control), 0.5, 1 and 2 mm were sprayed twice on 10 year-old ‘bidaneh sefid’ grape vines at full bloom stage and changes in leaf soluble carbohydrates, proline and protein levels were m...
