iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
In vitro evaluations of salinity (NaCI) effects on three potato cultivars (Atlanta, Shepody and Shilbilaty ) were investigated with five NaCI levels ( 0, 25, 50, 75 and100 mM) by using single node explants. Significant differences were noticed among the cultivars followed by different NaCl levels. Salinity stress gradually depressed plant growth and root development with increased NaCl concentr...

soil and water sources salinity are important constrains which threat the sustainable agriculture production in iran. in order to evaluate the effect of different antioxidants and salinity levels on germination and seedling properties of two medicinal species (cnicus benedictus l.), and (cichorium intybus l.), an experiment was conducted using a factorial based on completely randomized design w...
In order to investigate the effects of priming methods on the improvement of seed germination indices and seedling growth of Lallemantia (Lallemantia Iberica) under different salinity levels, two factorial experiment in a randomized complete block design were carried out in the seed technology laboratory of Agricultural Sciences and Natural Resources University of Khuzestan in 2018-2019. In the...
organic compost can reduce various plant stresses, because of its porous structure, high water storage capacity, and existence of some substances resembling hormones and plant growth regulators. this study was performed to investigate interactions of different levels of vermicompost extract and salinity stress on morphological characteristics of bean seedlings. the experiment was conducted in c...
abstract a greenhouse experiment was conducted to study the effects of soil copper (cu) and salinity application on photosynthesis parameters, enzyme activity and anatomical structure of two pistachio cultivars. a factorial greenhouse experiment was carried out as completely randomized design with three replications. treatments consisted of four cu levels (0, 2.5, 5, and 7.5 mg kg-1soil as cuso...
abstract for evaluating nacl salinity effect on some physiological and qualitative attributes of five winter canola cultivars, an experiment was conducted in a rcd base factorial in three replicates in greenhouse of east azarbaijan agricultural research center in 2008. five salinity levels as 0, 50, 100, 150 and 200 mm nacl treated as first factor on five rape seed (fornax, licord, elite, slm04...
in order to investigate the effects of supplementary calcium chloride and potassium nitrate on plant growth of ammi (carum copticum l.) in different salinity levels and nutrient solutions (ns), an experiment based on randomized complete block design (rcbd) with factorial arrangement was conducted under greenhouse condition in the faculty of agriculture, vali-e-asr university of rafsanjan, durin...
