The successful colonization of plant growth promoting rhizobacteria (PGPR) in the rhizosphere is an initial and compulsory step in the protection of plants from soil-borne pathogens. Therefore, it is necessary to evaluate the role of root exudates in the colonization of PGPR. Banana root exudates were analyzed by high pressure liquid chromatography (HPLC) which revealed exudates contained sever...

Several chemical changes in soil are associated with plant growth-promoting rhizobacteria (PGPR). Some bacterial strains directly regulate plant physiology by mimicking synthesis of plant hormones, whereas others increase mineral and nitrogen availability in the soil as a way to augment growth. Identification of bacterial chemical messengers that trigger growth promotion has been limited in par...

Seed inoculation with plant growth promoting rhizobacteria (PGPR) is an ideal tool to supply the soil with a high density of beneficial microorganisms. However, maintaining viable microorganisms is a major problem during seed treatment and storage. In this work, an evaluation was made of the effect of bacterial immobilization in nanofibers on the stability (viability and maintenance of benefici...

Area around the root zone i.e. rhizosphere is a rich environment for plant growth promoting bacteria (PGPR) which can be utilized in many way to improve the growth of crop and yield. In agriculture one of the limiting factors is providing plant nutrition particularly nitrogen and phosphorus to the crop. Different Plant-Growth Promoting Rhizobacteria (PGPR) such as Azospirillum, Azotobacter, Bac...

The potential of plant growth-promoting rhizobacteria (PGPR) to improve growth and nutrient acquisition has received increased attention. This study investigated the synergistic effects combining PGPR Paraburkholderia sp. SOS3 with addition inorganic N fertilizer (iN) or a combined application organic manure-based (iNoN) at low high levels fertilization on Macadamia integrifolia seedling growth...

گیاهان در همزیستی با قارچهای میکوریز آربوسکولار1 (amf) علاوه بر جذب بیشتر عناصر غذایی و آب، می توانند مقاومت خود را در برابر تنشهای محیطی از قبیل شوری و یا خشکی افزایش دهند. تصور می رود حضور برخی از باکتریهای محرک رشد گیاه2 (pgpr) مخصوصاً سودوموناسها در ریزوسفر چنین گیاهانی احتمالاً اثر هم افزایی3 داشته و اثرات مثبت قارچهای میکوریز را تشدید کنند. در این تحقیق گیاه گوجه فرنگی رقم super strain b در...

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...

Salinity is the major environmental factor limiting plant growth and productivity. Under salinity conditions, plant growth is affected by a number of factors such as hormonal and nutritional imbalance, ion toxicity, physiological disorders, susceptibility to diseases, etc. Plant growth under stress conditions may be enhanced by the application of microbial inoculation including plant growth pro...
