to breaking dormancy as well as the effect of light, temperature, salinity and drought stress on germination of cutleaf mignonette seeds, experiments were conducted at the research laboratory of birjand faculty of agriculture in 2009. immersion in sulfuric acid (96%) for 30 seconds under continuous dark regime resulted in the highest germinability (73%) and the lowest germination (8%). was obse...

pistachio is one of the most important export items in iran, comprising more than 23% of iran non-oil exports. yazd is considered as the second biggest province of iran from the viewpoint of pistachio production, standing after kerman province. since frostbite phenomenon, especially, strong spring frostbite, has incurred many damages into pistachio gardens of this area, it is necessary to study...

Dielectric behavior of doped poly (methyl acrylate) (PMA) Conducting polymer has been investigated in electret state. The permittivity and loss factor have been obtained at varying temperatures from 30 to 230C and different frequencies 05,10,25 and 50 kHz for different electrode configurations of doped poly (methyl acrylate) (PMA) conducting polymer films of 25μm thickness. The capacitances are...

The V kappa10 family of murine light chain Ig genes is composed of three members, two of which (V kappa 10A and V kappa 10B) are well used. V kappa 10C, the third member of this family, is not detected in any expressed Abs. Our previous work showed that V kappa 10C is structurally functional and can recombine, but mRNA levels in spleen were extremely low relative to those of V kappa 10A and V k...

Temperature was an important factor in growth, development and reproduction of Meloidogyne hapla in lettuce. Growth, as measured by increase in diameter of females, was not appreciably different at the intermediate (21.1 C night and 26.7 C day) and high (26.7 C night and 32.2 C day) temperature regimes, but was considerably less at the low temperature regime (15.5 C night and 21.1 C day) than a...

Influence of storage temperature on the shelf life of the pasteurized milk and the enzymatic activity of psychrotrophic bacteria in whole and skimmed pasteurized milk were the main goals of the presented work. It was demonstrated that the storage temperature of 10C reduces the shelf life of pasteurized milk to one third in comparison with a storage at 4 C. The average shelf life of the full cre...

Small amounts (10–25 g; 6.3–20.8 cm 2 inoculated area) of raw ground beef, intact beef, pork and chicken (dark and white meat),and bratwurst and cured corned beef were inoculated with Salmonella serovars and Escherichia coli O157:H7, refrigerated 24 h at 5C, and then held either at 10C ( ± 1C) for up to 8 h or at room temperature (22C ± 2C) for up to 2 h. Except for a 0.2 log CFU increase in Sa...

A five-strain rifampicin-resistant Listeria monocytogenes cocktail (ca. 3.0 log10 cfu/g) was introduced as a postpasteurization contaminant in queso fresco (QF) that was manufactured using a commercial procedure. L. monocytogenes was either inoculated into (IN) the curds before forming the cheese block or onto (ON) slices (52– 66 g), individually vacuum-packed and stored at 4 and 10C. Growth wa...
