In order to investigate the effect of Plant Growth Promoting Rhizobacteria (PGPR) and rhizobium bacteria on grain yield and some agronomic traits of mungbean (Vigna radiate L.), an experiment was carried out based on randomized complete block design with three replications in Malekshahi, Ilam province, Iran during 2012-2013 cropping season. Experimental treatments consisted of control treatment...

Bacteria are abundantly present in the soil, interact with plant roots in the rhizosphere and enhance plant growth and development in certain instances. The plant growth promoting rhizobacteria (PGPR) develop a mutualistic relationship with the host plants and gives a benefit to them through N2 fixation by nitrogenase, nitrate reductase activity, siderophore production, and phytohormone secreti...

With the purpose of Plant Growth Promoting Rhizobacteria (PGPR) isolation, several authors have sampled different wetlands in northern half Argentina. However, to date, we do not know existence microbiological studies conducted Patagonian salt marshes, and concretely, concerning isolation PGPR. The present work was heavy metal polluted San Antonio marsh, two areas with grade pollution. In those...

The aim of this study was to inventory the types of plant growth-promoting rhizobacteria (PGPR) present in the rhizosphere of plants grown in soils contaminated with heavy metals, recalcitrant organics, petroleum sewage or salinity in China. We screened 1223 isolates for antifungal activity and about 24% inhibited Rhizoctonia solani or Sclerotinia sclerotiorum. Twenty-four strains inhibitory to...

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...

Plant growth promoting rhizobacteria can affect plant growth by different direct and indirect mechanisms [1]. PGPR influence direct growth promotion of plants by fixing atmospheric nitrogen, solubilizing insoluble phosphates, secreting hormones such as IAA, GAs, and Kinetics besides ACC deaminase production, which helps in regulation of ethylene. Induced systemic resistance (ISR), antibiosis, c...

Abstract Plant Growth Promoting Rhizobacteria (PGPR) is consortium of active bacteria colonize root plants that play important role in improving growth. This research aims to figure out effect PGPR on wati ( Piper methysticum Forst) seedling conducted at the Screen House Yasa Mulya Village, Tanah Miring District, Merauke, Papua. study used Group Random Design as experimental design consisted 5 ...

a study was conducted to evaluate the effects of plant growth promoting rhizobacteria (pgpr) inoculants including four strains of azotobacter chroococcum, azospirillum lipoferum, a. brasilense and pseudomonas fluorescence on dry matter accumulation of late maturing maize(zea mays l.) hybrids, sc704, sc700 and a promising single cross b73×k18. a factorial experiment was conducted in research fie...

In arid regions, starchy agricultural products such as wheat and rice provide essential carbohydrates, minerals, fibers vitamins. However, drought, desiccation, high salinity, potentially toxic metals hydrocarbon accumulation are among the most notable stresses affecting soil quality cereal production in environments. Certain bacteria, referred to Plant Growth-Promoting Rhizobacteria (PGPR), co...

The application of plant growth promoting rhizobacteria (PGPR) to agro-ecosystems is considered to have the potential for improving plant growth in extreme environments featured by water shortage. Herein, we isolated bacterial strains from foxtail millet (Setaria italica L.), a drought-tolerant crop cultivated in semiarid regions in the northeast of China. Four isolates were initially selected ...
