abstract: advertisements are the most accessible type of authentic materials, and this is one reason why they are used more and more in english teaching classes. for this cause, studies in the field of advertisements are very widespread nowadays. for pun is one aspect which makes advertisements more interesting, it is used more than before in advertisements. use of puns makes an advertisement m...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
Drought as one of the most important environmental stresses causes serious threats in amount and efficiency of crop productions. To evaluate drought resistance by using drought tolerance indices in safflower varieties, a research was conducted at the Research Farm of Bu-Ali Sina University. Experiment was planed as split-plot on the basis of randomized complete block design with three replicati...
drought is the most restricting factor in agricultural production in arid and semi-arid regions. this research was conducted on 19 facultative and winter wheat genotypes grown under normal irrigation (n), early post-anthesis (s1), and late post-anthesis (s2) drought stress conditions. the experiments were conducted at karadj, arak, and jolgehrokh agricultural research stations in iran, during 2...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
In the present study, in order to evaluate the drought tolerance indices and their relationship with ISSR markers, 12 rapeseed genotypes were studied using a factorial experiment based on completely randomized block design under the three irrigation treatments (control and irrigation after drainage of 60 and 85% moisture content) in the greenhouse of Mohaghegh Ardabili University, Iran. Drought...
This research was carried out to evaluate the effect of drought stress on grain yield and qualitative traits in some Iranian landraces of confectionary sunflower. Fifty six confectionary sunflower landraces were evaluated using three different water treatment conditions with three separate rectangular 7 × 8 lattice design with two replications. Irrigation treatments were as follows optimum irri...
To investigate the effects of drought stress on the water stress, osmotic adjustment and stay green of sorghum genotypes and their relationship with grain yield, a split-plot on randomized complete block design with three replications was conducted at the experimental field of Seed and Plant Improvement Institute, Karaj, Iran in 2015. The main factor was three treatments: control (irrigation af...
to evaluate the effects of water deficit stress in barley germplasm collection of national gene bank ofiran, 25 genotypes collected from arid and semi arid provinces of iran and 3 sample cultivars werestudied in two environments including: non-stressed and water deficit stress. agronomical, phenologicaland morphological traits were measured. stress indices were calculated to determine tolerant ...
Extended Abstract Introduction and Objective: The cow cockle has a great potential for producing medicinal products due to its triterpenoid saponins. This experiment was aimed to investigate different cow cockle ecotypes under drought stress conditions and select the tolerant ecotype(s) based on agronomic traits using selection indices under different irrigation regimes. Materials and Methods...
