in order to evaluate the effects of different plant growth promoting rhizobacteria (pgpr) on yield and yield components of sesame, an experiment was conducted in the form of randomized complete block design with three replications at research station, faculty of agriculture, ferdowsi university of mashhad in year 2009. treatments were: 1) nitragin (containing of azotobacter sp., azospirillum sp...
Rhizosphere is a wealthy location of microbes, ecological niche and should be explored for potential plant growth promoting rhizobacteria (PGPR), which developing as bioinoculants for interact with plant roots and enhancement of yield of crop plants. There are several plant growth promoting rhizobacterial (PGPR) inoculants that seems to promote plant growth through different mechanism such as I...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
Among abiotic stresses, drought is considered as the most important growth limiting factor, especially in arid and semiarid regions. Drought impacts can be adjusted by soil microorganisms. Accordingly, the present study was organized in order to the increase the tolerance of lemongrass (Cymbopogon citratus)to drought using plant growth promoting rhizobacteria (PGPR). Treatments were wa...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
the plant promoting bacteria as biological fertilizers play an important role in increasing productivity and improving plant growth in stress condition. in order to evaluate the ability of plant promoting bacteria rhizobacteria on germination and growth of corn under salinity conditions, a pot experiment was conducted in factorial based on randomized complete block design with three replication...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
Phytoremediation is a promising method for remediation of heavy metals (HMs) contaminated environments. However, the main failures are the limited bioavailabilty of HMs such as lead (Pb) in the soil and/or suppressed plant growth in contaminated sites. These limitations specifically occur in semi-arid zone environments such as calcareous soils. Arbuscular mycorrhizal fungi (AMF) and plant growt...
plant growth promoting rhizobacteria and arbuscular mycorrhizal fungi can inhanced plant growth by increasing nutrient uptake. in order to investigate the effect of pgpr and amf on some morphological parameters, macro (nitrogen, phosphorus, potassium, calcium and magnesium) and micro (iron, zinc and copper) nutrients uptake, percentage of root colonization and some morphological factors of pepp...
implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
