laboratory studies were conducted to compare the relative fitness of clodinafop-propargyl herbicide resistant lolium rigidum accessions with their clodinafop-propargyl susceptible counterparts in 2014. factors evaluated were lolium populations at constant salinity stress (0, 5, 10, 15, 20 and 25 ds cm2) and water stress (0, -3, -6, -9, -12 and -15 bar). the maximum germination in salinity stres...
coriander is one of the important economic plants for medicinal production. this investigation consists of the effects of different drip irrigation (surface and subsurface) and furrow irrigation methods on grain, oil and essential of coriander. for this purpose, experiment over the past two years (2010 and 2011) in a randomized complete block was designed in three replications. treatments were ...
this research was conducted to study the effects of water deficiency stress, nitrogen application rates, and plant population on water use efficiency and nitrogen of oily sunflower in 2007-2008 agriculture and research center of west-azerbaijan. the study was consisted split-split-plot experiments using randomized complete block design with 3 replications. the factor main was consisted irrigati...
Considering the high water requirement of grass during growth stages and the limitation of irrigation sources, it is important to find a suitable way to reduce the water requirement of the lawns as cover plants used in the Landscape. The purpose of this study was to investigate the effect of 2,4,5-T on the induction of callus from the hypocotyl explant in Kentucky bluegrass, induce in vitro dro...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
hedging is a multi-purpose rhetorical strategy which is usually used in scientific arguments to secure ratification of claims, reduce the risk of negation, avoid conflict, manage disagreement and leave room for the audience to assess presented information. hedges are frequently used in research articles to mitigate the findings of research endeavors. the present research aims to investigate the...
irrigation requirement equals the difference between water requirement and effective rainfall which can be estimated by considering the water application efficiency. the values of water requirement and irrigation requirement of sugar beet have been reported using netwat program in different regions ofiran. however, the mean values were used in this program; therefore the values of water and irr...
the purpose of this study was to investigate iranian efl learners’ beliefs about the role of rote learning (rl) in vocabulary learning strategies; besides, the study examined if english proficiency would influence learners’ vocabulary learning strategy use. this study addresses the need for a clear understanding of the role of rl in efl vocabulary learning by looking at iranian efl learners’ ow...
this experiment was conducted to increase the resistance of tiger barb (capoeta tetrazona ) against environmental stress by feeding brackish water gammarus sp. powder as supplementary diet in three levels (25%, 50% and 75%) and three replicates pe group compared to control group for 60 days. fishes was fed with 4 diet treatment containea of: 100% artificial diet (control group), 25% brakish wat...
piriformospora indica, a cultivable root colonizing endophytic fungus of sebacinales, promotes plant growth and confers resistance against biotic and abiotic stress. the fungus has also the ability to colonize the roots of many varieties of plant species. the goal of present study was to clarify the colonization ability of p.indica in artichoke roots and the respond of plant to water stress. re...
