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 me...

in order to evaluate the effect of different levels of drought stress on some physiological parameters in grapevine, a potted experiment with iranian grapevine cultivars ‘sahani’, ‘bidane-sefid’ and ‘farkhii’ was conducted in summer of 2008. the experiment was performed while employing four drought stress (water potential of soil, ?s= -0.2, -0.6, -1, -1.5 mpa) treatments each in three replicati...

The Caspian frisian roach (Rutilus frisii kutum), economically a very important fish species in Iran, is propagated in fishponds, reared into the rivers in fingerling size and then harvested from the Caspian Sea in adult stage. We found six monogenean parasites on the Caspian frisian roach including five Dactylogyrus spp. on fingerlings cultured in fishponds and rivers and two Dactylogyrus spp....

chilling is an important environmental stress that influences the yield and quality of many agricultural crops. different plants use different systems to endure this stress and minimize its effects. one of these systems is enzymatic reaction. to find out more about responses of different grapevine species and cultivars to the low temperature conditions, their enzymatic changes were evaluated in...

in order to investigate the effect of two spermidine concentrations (0.5 and 1 µ m ) on in vitro gynogenesis of six onion accessions from khorasan province this research was carried out. results showed that the highest and lowest percentage of gynogenesis rate was belonged to m2 and m5 media, respectively. the highest (1.41) and lowest (0.33) percentage of gynogenic embryo were belonged to rosh...

Semiran city-castle consists of a series monuments dated in the 10th century AD1, located on banks Qezel Owzan River, north-western Iran. On this river, Sefid-rud Dam has been built (1956-1962), behind which lake developed. At time its dewatering, it turned landscape into peninsula, causing significant damage to ancient sites.
