drought stress is the main limiting factor in the arid and semi-arid region of the world. this research was conducted to evaluate drought tolerance in different accessions of sainfoin for yield, morphological and agronomic traits in 2010. twenty one accessions (landraces and varieties) were evaluated in two environments including drought stress and non-stress conditions for four harvests accord...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
A biotic stresses can directly or indirectly affect the physiological status of an organism by altering its metabolism, growth, and development. In order to study the effect of drought stress on Citrullus colocynthis samples a factorial experiment was conducted in Horticultural science Department of University of Tehran in 2013. The first factor was two accessions of Citrullus colocynthis (Yazd...
in order to evaluate the effect of drought stress on grain yield and its components of fennel accessions, a field experiment was conducted as a split plot based on complete randomized block design with three replications. this experiment was conducted in research farm of agricultural faculty of zanjan university in 2012. in this study water stress in two levels included control and drought stre...
in order to study the response of five watermelon accessions (tn.93.765, tn.93.469, tn.93.485, tn.93.425 and tn.93.330) to drought stress an experiment was conducted as factorial experiment in randomized completely block design with three replications. this research were investigated in hydroponic system with four levels of osmotic potential induced by poly ethylene glycol 6000 (peg) including ...
To examine the genetic variation for drought stress in chamomile, eight accessions belonging to four species were evaluated under both field and greenhouse conditions using normal and late season drought stress. In the field experiment drought stress were initiated with irrigation cease at the commencement of flowering time. In greenhouse experiment, irrigation carried out at flower initiation ...
In this experiment 36 accessions of seven species of Brassica genus were evaluated under field condition (for study of genetic variation) and under laboratory condition (for study seedling drought tolerance) in 2012 at Isfahan university of technology research farm. The statistic design in field was completely randomized block with three replications. Results of field assessments were suggestiv...
this study investigated the effects of planning on second-language written production with regard to task type. the participants were 75 iranian learners of english as a foreign language attending a private foreign language institution. they were asked to complete two different types of writing tasks (expository writing task and argumentative writing task) in different planned conditions (indiv...
This study was carried out to evaluate drought stress tolerance in Thymus kotschyanus accessions using a factorial experiment based on a Completely Randomized Design (CRD) with 5 replications during 2013-2014 in Qom, Iran. The first factor was the accession with 17 levels and the second factor was drought stress with three levels of irrigation including 80% (control), 60% and 40% Field Capacity...
Low-phosphorus (LP) stress is a global problem for maize production and has been exacerbated by breeding activities that have reduced the genetic diversity of maize. Although LP tolerance in maize has been previously evaluated, the evaluations were generally performed with only a small number of accessions or with samples collected from a limited area. In this research, 826 maize accessions (in...
