In order to evaluate on Glutamine Syntetase gene expression as well as amount of protein, chlorophyll and oxidative index of TBARM the experiment has been carried out using Brassica napus (Falcon cv.) in research greenhouse condition. The drought stress treatments were included -0.5, -1, -2, -4 and -6 bar that by using of equivalent water (6.5, 6, 4.7, 3, 1.1 litr respectively) have been irriga...
This paper fortifies and defends the so called Sufficiency Argument (SA) against Classical Invariantism. In Sect. 2, I explain the version of the SA formulated but then rejected by Brown (2008a). In Sect. 3, I show how cases described by Hawthorne (2004), Brown (2008b), and Lackey (forthcoming) threaten to undermine one or the other of the SA’s least secure premises. In Sect. 4, I buttress one ...
bserved by many teachers that most of the time, mumbling and searching for their intended words, students complain why they have forgotten the words they have learned in the previous semesters. they ask for some new ways that may help them to recall and apply the learned words more efficiently, since as they declare one of the most important skills in foreign language learning is having a g...
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
Investigating the crop response to the deficit irrigation and evaluating the effect of drought stress on plant is one of the most important issues in crop production. In these circumstances, the use of organic fertilizers can play a mitigative role. Hence, an experiment was laid out as split plot based on randomized complete blocks design with three replications in Research Farm of University o...
abstract: the present study is about prophet ishmael, some parts of his life; his personality in the quran and the bible; and the comparison of the content of these two religious books. compilation of the study has been done with a new perspective and new presentation approach. since prophets have been human beings’ role model and their life has been a perfect example for humanity in all ages,...
in order to investigate the effect of silicon application on some physiological characteristics and growth of wheat (triticum aestivum l.) under late drought stress condition, an experiment was conducted at the agriculture and natural resources university of ramin, khuzestan during year 2012. the experiment was conducted in the open environment as factorial randomized complete block design with...
چکیده نمایشگاه های جهانی یا اکسپو عنوانی ست که از سال 1851 میلادی در لندن توسط همسر ملکه انگلستان شکل گرفت ، هدف اولیه این نمایشگاه ها نمایش دستاورد های صنعتی بود، اما در طول 165 سال که این نمایشگاه های برگزار گردیدند ، رویکرد آنها تغییر کرده است . در هر دوره به یک شعار که در واقع دغدغه اصلی جهان، در آن زمان بوده است ، پاسخ داده شده و راه حل کشور های مختلف در مورد آن موضوع به نمایش گذارده شد...
Drought stress is a major constraint for crop production in arid and semiarid regions, such as Iran. In this study the effect of 5-aminolevolinic acid (ALA), the new plant growth regulator, on Coriander (Corianderum sativum L.) plants under drought stress was studied. The layout was factorial experiment in randomized complete block design (RCBD) with 3 levels of drought stress including stress-...
Oil seed rape (Brasica napus) is an important crop, which is cultivated in Iran for oil production. As a management practice deficit irrigation strategy is applied to cope with water shortages, especially during drought periods. This research was conducted to study the effect of water stress on physiological parameter of oil seed rape in the experimental research field of Collage of Agriculture...
