Nursery experiments were conducted to select the suitable biofertilizers combination attain quality seedlings of Neem. The such as Azospirillum, Paenibacillus and AM fungus (Glomus fasciculatum) inoculated by separately various combinations with each other at time seed sowing. Shoot length, root collar diameter, shoot dry weight recorded on 80 days after treatment. Results showed that total len...

azospirillum is a well-studied genus of plant growth-promoting bacteria. phytohormone production by pgpr is considered as one of the effective factor to increase the tomato yield significantly. in order to study the effect of azospirillum inoculant on on growth characteristics and yields of tomato, three strain of azospirillum were isolated, identified, and purified from tehran suburb soils. to...

Nodulation of soybean (Glycine max) root hairs by the nitrogen-fixing symbiotic bacterium Bradyrhizobium japonicum is a complex process coordinated by the mutual exchange of diffusible signal molecules. A metabolomic study was performed to identify small molecules produced in roots and root hairs during the rhizobial infection process. Metabolites extracted from roots and root hairs mock inocul...

objective: the inoculation of substrates with arbuscular mycorrhizal fungi (amf) is one of the most important effective strategies applied and one of the aims of sustainable agriculture. methods: this experiment was conducted to evaluate the effects of amf inoculation (0, 2.5, and 5 w/w) on morpho-physiological traits such as flower and root dry weight, water-use efficiency and antioxidant capa...

The duration of the embryogenic development of Nacobbus aberrans (= N. batatiformis) took 9-10 days at 25 C and 51 days at 15 C. The J molted in the egg; hence the Je emerged from the egg. The effect of distilled water attd root leachates of kochia and sugarbeet was investigated at 5, 10, 15, 20, and 25 C. Root leachates did not significantly affect the percent of cumulative hatch of eggs, but ...

abstract the objective of this study was to assess the effects of few arbuscular mycorrhizal fungi and plant growth promoting rhizobacteria on the growth and yield indices of two wheat varieties in a saline soil (ec=10/1 dsm-1). a factorial experiment with completely randomized design with four replications was conducted to investigate the effects of three levels of fungal inoculation (non inoc...

to study  the effect of powdery mildew on sugar beet yield and percentage of sugar losses sugar percent losses, ten genotypes were compared in a factorial  experiment based on  randomized complete block design with 3 replications and two factors. the first factor was spraying treatment with two levels and the second were genotypes. inoculation was carried out using the pathogens' conidial ...

AIMS To evaluate the colonization process of sugarcane plantlets and hydroponically grown rice seedlings by Gluconacetobacter diazotrophicus strain PAL5 marked with the gusA and gfp reporter genes. METHODS AND RESULTS Sugarcane plantlets inoculated in vitro with PAL5 carrying the gfp::gusA plasmid pHRGFPGUS did not present green fluorescence, but beta-glucuronidase (GUS)-stained bacteria coul...

The effects of arbuscular mycorrhizal (AM) fungus (Glomus mosseae) and phosphorus (P) addition (100 mg/kg soil) on arsenic (As) uptake by maize plants (Zea mays L.) from an As-contaminated soil were examined in a glasshouse experiment. Non-mycorrhizal and zero-P addition controls were included. Plant biomass and concentrations and uptake of As, P, and other nutrients, AM colonization, root leng...

plant establishment is the most critical stage in biological renovation of rangelands. the processes which normally fails, due to the harsh conditions in the arid and semiarid environments. new technologies may be used to overcome this problem. the purpose of the present study was to investigate the possibility of enhancing seedling establishment and growth rate of alfalfa (medicago sativa l.) ...
