Salicylic acid (SA) is a naturally occurring plant hormone that has positive effects on growth and tolerance to biotic and abiotic stresses, especially salinity in plants. To evaluate the effects of SA and salt stress on some morphological and physiological traits and quantitative activities of antioxidant enzymes on thyme (Thymus vulgaris), was conducted a factorial pot experiment based on com...

in order to study the effect of ca, k, and mn foliar spray on vegetative traits of safflower (padideh cultivar) under salt stress, a factorial experiment was conducted based on randomized complete blocks design with three replications in vali-asr university greenhouse. factors included salinity with four levels representing 0, 500, 1000, and 1500 mg nacl kg -1, and foliar spray with four level ...

abstract plant- growth promoting rhizobacteria enhance plant growth and yield directly and or indirectly. a factorial experiment was conducted in greenhouse to determine the efficacy of four strains of fluorescent pseudomonas on wheat yield and yield component under saline conditions. the experiment was carried out with the following treatments (non –inoculation control and inoculation with p.f...

abstract irrigation planning and management requires continious monitoring and measurements of soil moisture content. application of gypsum blockes (gb) are common in soil moisture measurements. gb readings are subjected to its geometry and soil solution concentration. this study was carried on 90 gb in research greenhouse of faculty agricultural, ferdowsi university of mashhad. at the begining...

ABSTRACT- Olive (Olea europaea L.) is one of the most valuable and widespread fruit trees in Iran. Salt stress-induced changes in membrane stability, photosynthesis and antioxidant enzyme activity were examined on four olive cultivars (Dakal, Shiraz, Zard and Amigdalifolia) by emphasizing the correlation between measured parameters and ion (K+, Na+) accumulation. Plants were subjected to four s...

Salinity stress as a major agricultural limiting factor may influence the chemical composition and bioactivity of Rosmarinus officinallis L. essential oils and leaf extracts. The application of salicylic acid (SA) hormone may alleviate salinity stress by modifying the chemical composition, gene expression and bioactivity of plant secondary metabolites. In this study, SA was applied to enhance s...

Salinity is a main and common stress which decreases the amount of agriculture products and natural plants in many areas of the world. In this study, the effect of salt stress on three varieties of Lotus corniculatus 'Karaj', 'Jolfa', and 'Ardabil' was investigated. Plants were cultured in hydroponic condition with four NaCl treatments (0, 50, 100, 150 mM). The amounts of proline, glycine betai...

in order to investigate the effects of saline waters on some soil characteristics, this experiment was conducted with three irrigation water salinity treatments contains 1.7-3.4, 8-9 and 11-12.5 dsm-1 (low, medium and high salinity) and two irrigation water managements with four replications in a wheat-fallow-sugar beet-safflower rotation. results show that in (1) irrigation management with low...
