Salinity is one of the most important abiotic stresses that limit crop growth and productivity. This study focuses on the effects of different strains of plant growth promoting rhizobacteria (PGPR) on the physiological responses of two wheat cultivars under normal and salt stress conditions. The wheat cultivars selected include one which is tolerant to salinity (Kavir) and one which is sensitiv...
despite the importance of drought stress in early stage of growth and plant establishment, it has usually been neglected as selection criteria in breeding programs. therefore, a population of recombinant inbred line derived from the cross “babax/seri m82” and their two parents were studied. the experiment was conducted in two randomized complete block designs with two replications under osmotic...
اثرات اسید سالیسیلیک بر برخی از ویژگیهای مورفو-فیزیولوژیکی و بیوشیمیایی دانهال گردو تحت تنش شوری
Salinity of water irrigation and soil are of the major factors affecting plant growth and productivity worldwide. In this research the effects of salicylic acid on some morpho-physiological and biochemical characteristics of walnut (Juglans regia) seedlings under salinity stress condition were studied. The experiment was a two-factor factorial experiment arranged in completely randomized design...

Improvement of plant nutrition is one of the approaches for augmenting the drought stress tolerance in plants. Due to low organic-matter content in most soils in arid and semi-arid regions of Iran, application of organic-wastes’ compost can increase water-holding capacity of the soil and improve plant nutrition. So, in this study, the interactive effects of soil moisture and municipal sewage-sl...
A pot experiment was conducted in order to study the effects of mycorhizal inoculation on the response of sorghum genotypes to salinity. The experiment was arranged as factorial in a randomized complete block design with three replications. In this study ten sorghum genotypes were tested under two levels of salinity (0 and 100 mM Nacl), and two inoculation (mycorhizae and control) treatments. T...
