abstract plants are exposed to stressful environmental conditions in the process of growth and development. one of the most important stresses is the salt stress which can limit the plant’s growth and yield. plants symbiosis with arbuscular mycorrhizal fungi in salt conditions can affect the plant’s yield as well as growth parameters. the plant’s growth in salt stressful conditions might be red...
the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
The use of plant growth hormones and beneficial microorganisms, could reduce the drought damage. The purpose of this study was to investigate the treatment with salicylic acid and inoculated with mycorrhizal fungi at different levels of irrigation on flax growth. A factorial experiment based on randomized complete blocks design with 3 replications was performed in growth chamber of college of a...
despite the different criticisms on contrastive analysis it has been proved that the results of it(when processed) can be useful in a tefl environment, specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims.the consonants,vowels,stress and intonation of the two languages are described by the same model...
Background: The composition of the planting beds and its microorganisms has a very important role on the establishment, growth and phytochemical performance of medicinal plants. Objective: The aim of this study was to determine the effect of different planting beds and inoculation of mycorrhizal fungus on the changes of stevioside, rebaudioside, and morpho-physiological traits of stevia. Meth...
seed inoculation by means of mycorrhizal fungi can alleviate the side-effects of fungicides on production of crops and their yields. an experiment was conducted in 2009 at the research field of islamic azad university, faculty of agriculture, mahdasht, karaj. in order to investigate the influence of different kinds of fungicides on colonization of mycorrhizal species and on grain yield in soybe...
THE SYMBIOSIS EFFECT OF VESICULAR-ARBUSCULAR MYCORRHIZA ON GROWTH OF POA BULBOSA (BULBOS BLUE GRASS)
Inoculation experiments were carried out in pot culture to determine the effects of VA fungi on the growth of Poa bulbosa. In this experiment, four treatments were used: 1. Strile soil without inoculation, 2. Strile soil plus inoculum, 3. Natural soil plus inoculum, and 4. Natural soil without inoculation. Inoculum was prepared from a suspension of mycorrhizal roots of Poa plants (Root c...
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
To evaluate the effect of Azospirillum and mycorrhizal soil fungi on nutrition Jerusalem artichoke crop (Helianthus tuberosus L.), determinations agronomic parameters health status plants were carried out under field conditions. The tests out, at time implantation culture: "seeds" inoculated with A. brasilense native fungi, generating four treatments including control co-inoculation consortium ...
