trifolium spp. are native plants in iran exhibiting good ground cover po-tential. salinity is a major environmental stress and today, 20% of the world cultivated areas and nearly half of all irrigated lands are affected by salinity. the main aim of this research was to study morphological and physiological adaptations of these native species under different salinity levels for urban landscape u...
salinity is one of the most limitation factors for crop production in agricultural systems due to the toxic effects and preventing water and nutrients absorption, in this research the efficiency of four strains of fluorescent pseudomonads on concentration of nutrient elements in rice was determined, under saline conditions. a pot experiment was carried out based on the factorial completely rand...
In order to investigate physiological and biochemical changes of wheat under stress residue of Imazethapyr herbicide (Imazethapyr), an experiment was conducted in a completely randomized design with four replications in greenhouse conditions at university of Mohaghegh Ardebili. The treatments consisted of five dose levels of herbicide Imazethapyr (0, 0.011, 0.022, 0.033 and 0.044 micrograms of ...
In order to evaluate the effects of salicylic acid on some physiological characteristics of common purslane (Portulacea oleracea L.) under NaCl stress, a factorial experiment based on completely randomized design with three replications was conducted in 2013 in research greenhouse of Faculty of Agriculture, University of Yasouj, Iran. Treatments were included of six levels of NaCl salinity (0, ...
Salt stress is one of the most chalanging abiotic stresses affecting natural productivity and causing significant croplosses worldwide. A greenhouse experiment was conducted to evaluate the response of two alfalfa cultivars (Bamiand Hamedani) to 6 levels of salinity (0 as control, 25, 50, 75, 100, 125 mM NaCl) at the College of Agriculture,Shiraz University, Shiraz, Iran in 2008. Plant dry weig...
In order to evaluate the tuber fresh weight and some physiological attributes of Agria potato cultivar in response to water deficit stress and mycorrhiza inoculation, a field trial was conducted as a split plot scheme based on randomized complete block design with three replications at the research site of Islamic Azad University, Tabriz Branch in 2012. Four water levels including: irrigation a...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
to study the physiological effects of different levels of salt stress on germination and on seedling stages, two seperate experiments were undertaken in rice research institute of iran, amol in 2006. the experiments were conducted in a completely randomized design of three replications in greenhouse. sixteen rice genotypes namely: ahlamitarum, shafagh, gharib, taromzavarak, khazar, mosatarom, g...
this ethnographic case study research was carried out in a private school setting in the context of iran. the research tried to explore the analysis and identity construction of a group of learners and teachers along with the content analysis of books on the basis of four types of commodified, political, national and narrative identities. how english language learners and teachers in an informa...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
