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...
background: some health-protecting secondary metabolites can be found at a higher concentration in the sprouts compared to other stages of plant growth. in addition, environmental stresses such as salt stress may be resulting in the increase or decrease of specific secondary metabolites in sprouts and plants. objective: evaluation the changes of trigonelline, nicotinic acid, and proline content...
The use of micronutrient fertilizers, such as zinc on the condition of natural limiting factors such as salinity can be a great help in the development of medicinal plants cultivated in many parts of the country. In order to study the response of Plantago ovata to zinc application under salt stress, a pot experiment was conducted in 2013, as factorial experiment based on a complete randomized d...
the following question poped up: is there any relationship between iranian high school efl learners reading comprehension and listening comprehension? then the following null hypothesis (ho) was developed to the test the above, mentioned question. "there is no relationship between high school efl learners reading comprehension and listening comprehension. for nearly 16 weeks, the experimental g...
Aloe vera is one of the medicinal plants, resistant to drought and high temperatures, that its gel has many applications in pharmaceutical, health and food industry. This experiment was conducted to determine the effects of salinity stress, caused by sodium chloride (NaCl) and calcium chloride (CaCl2), on leaf weight, gel content and ratio of some nutrients in Aloe vera, in Research G...
In order to evaluate the effects of seed priming with salicylic acid (SA) (0, 2, 10, and 20 mM) to increase salt tolerance (0, 50, 100, 150, and 200 mM NaCl) in medicinal plant Dracocephalum moldavica at seed germination, an experiment was conducted as factorial in a completely randomized design with four replicates. The assessed parameters included germination percentage and rate, len...
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...
To study the effect of salinity on photosynthesis pigments, fluorescence and antioxidants of three varieties of peanut leaf as an indicator of resistance to salinity, research was carried out as factorial arrangement based on completely randomized design with three replications in the greenhouse of University of Guilan in 2013. The experiment consisted of a combination of 4 different salinity l...
abstract this quasi-experimental study was aimed at examining the impact of storyline complexity on the grammatical accuracy and complexity of advanced and intermediate efl learners. a total of 65 advanced and intermediate efl learners were selected from iran language institute (ili). an intact group including 35 intermediate participants and another intact group with 30 advanced participants ...
Salinity is one of the most brutal environmental stresses limiting the productivity of agricultural crops. In order to determine the effect of humic acid on some morphological and physiological characteristics and uptake of elements by strawberry (Fragaria ananassa Duch. cv. Sabrina) under salinity stress, a greenhouse factorial experiment was conducted with three factors including two treatmen...
