ذرت (zea mays l..) یکی از مهم ترین گیاهانی است که زراعت آن در کشور رو به توسعه است. این پژوهش مزرعه ای به منظور بررسی جنبه های اگرواکولوژیک کاربرد کودهای زیستی (بیولوژیک) از نوع باکتری های ترغیب کننده رشد گیاهplant growth promoting rhizobacteria (pgpr) شامل : azotobacter azospirillum , azospirillum lipoferum , chrococcoom brasilense و pseudomonas fluorescens بر سبز کردن گیاهچه، فنولوژی ( زیستگر...
As a natural engineer, Plant Growth Promoting Rhizobacteria (PGPR) play an important role in increasing plant growth, yield and enhancing tolerance to stressful conditions. These beneficial bacteria take up their position the rhizosphere, around plants’ root tissues. They may be in, or on host tissues help provide nutrients plants. For sustainable agriculture, PGPR transmit extensive assistance...
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...
Solanum lycocarpum St. Hil. is an endemic plant of the Brazilian tropical savannah (cerrado) that capable growing on acidic and nutrient-poor land, ability which attracts attention to its rhizospheric microbiota, including growth-promoting rhizobacteria (PGPR). In this work, 131 bacterial strains were isolated from rhizosphere samples S. tested in vitro for direct mechanisms growth promotion (b...
Being sessile in nature, plants have to withstand various adverse environmental stress conditions including both biotic and abiotic stresses. Comparatively, abiotic stresses such as drought, salinity, high temperature, and cold pose major threat to agriculture by negatively impacting plant growth and yield worldwide. Rice is one of the most widely consumed staple cereals across the globe, the p...
A 3 year field study was conducted with field corn from 2005 to 2007 to test the hypothesis that microbial inoculants that increase plant growth and yield can enhance nutrient uptake, and thereby remove more nutrients, especially N, P, and K from the field as part of an integrated nutrient management system. The field trial evaluated microbial inoculants, which include a commercially available ...
Doxorubicin (DOX)-loaded water-in-oil-in-water (W/O/W) microemulsions were produced using a shirasu-porous-glass (SPG) membrane emulsification technique. Soybean oil was used as the oil phase; polyglycerol polyricinoleate (PGPR) or tetraglycerol polyricinoleate (TGPR) was used as the surfactant to stabilize the feed W/O emulsions, while Tween 20 was used in the external water phase to stabilize...
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...
Paenibacillus polymyxa SC2 is an important plant growth-promoting rhizobacterium (PGPR). Here, we report the complete genome sequence of P. polymyxa SC2. Multiple sets of functional genes have been found in the genome. As far as we know, this is the first complete genome sequence of Paenibacillus polymyxa.
Eight endophytic isolates assigned to Pseudomonas, Azospirillum, and Bacillus genera according to pheno-genotypic features were retrieved from barley seeds under selective pressure for nitrogen-fixers. Genetic relationships among related isolates were investigated through RAPD. Six isolates displayed nitrogen-fixing ability, while all could biosynthesize indolacetic acid in vitro and showed no ...
