to study the effects of drought stress and foliar application with salicylic acid on yield andit’s components and percentage of essential oil of nigella sativa l., a field experiment was conducted as split plot based on randomized complete block design with three replications at research farm of shahid bahonar university of kerman during growing season of 2013- 2014. the main factor was drought...

to study the tolerance of genotypes under terminal drought stress, 20 promising winter and facultative bread wheat genotypes were evaluated at karadj, ardebil, arak and hamedan agricultural research stations during 2001-02 cropping season. the experimental design in all the locations was randomized complete block of three replications. grain yield (yld), harvest index (hi), grain number per spi...

mechanisms of drought stress tolerance of gf677 rootstock, peach and almond hybrid, (prunus persica × prunus amygdalus) were studied under in vitro conditions. plantlets of gf677 rootstock were subcultured into the murashige and skoog (ms) solid proliferation medium containing 1 mg/l ba (6-benzyladenine) and 0.1 mg/l naa (naphthaline acetic acid) in four drought stress levels 0 (control), 10, 2...

in order to determine the lipids and lipoproteins profiles in iranian khouzestanian arab horses, blood samples were collected from the jugular vein of 77 horses(47 female, 30 male) from different age groups(< 6, 7-12, 12-36, 37-60, 61- 69 and > 96 months). serum cholesterol and triglyceride were measured by enzymatic methods and lipoproteins by precipitation methods. the results were analyzed b...

this research was carried at the university of reading in 1999. the aim was to estimate the effects of 18 hd-1 (long-day, ld) and 12 hd-1 (short-day, sd) light exposure duration of plants before bolting or flowering on time to bolt and flower in two bolting susceptible (bsg, ic1) and bolting resistant (brg, saxon) genotypes of sugar beet. so, two experiments were conducted. the experiments were...

small precipitation with temporal and spatial variation of rainfall is the main responsible factors on flood occurrence in arid and semi arid regions. floods in their regions usually contain high concentration of sediments which when they are deposited on the surface of lands, they change the properties of soils of the area. in this research, the effect of floodwater spreading on physic-chemica...

in order to evaluate the waterlogging stress effects on yield and yield components of rapeseed, a pot experiment was conducted at gorgan university of agricultural sciences and natural resources during 2010-2011. the experiment design was completely randomized with factorial arrangement and three replications. examined factors were developmental stage (seedling, stem elongation, flowering and g...

background: as we all know, sperm has the capacity to take up foreign dna, therefore, sperm mediated gen transfer can be an inexpensive and simple method in animal transgenesis in various species. however, there is not sufficient evidence of dna uptake by ovine spermatozoa. objectives: the purpose of the present study was to examine the uptake of human lysozyme gene contained plasmid (pegfp-ire...

background:     purpose:     methods:     results:     conclusion:

this study was carried out to evaluate the effect of commercial live bakery’s’ yeast( saccharomyces cerevisiae ), (marketed as amax), on growth and survival of persian sturgeon( acipenser persicus) larvae (74.9 ± 9.7mg) during 30 days. sturgeon larvae were fed on daphnia magna enriched at three suspensions of yeast, amax, (0, 50, 100, and 150 mg yeast per litter). the feeding level was 30 perce...
