One of the most important functions of Azospirillum is to fix atmospheric N to soil and making it available to plants Bashan and de-Bashan, The excessive consumption of chemical fertilizers poses numerous adverse impacts on the environment and many life forms on earth.

The association with A.

Response of barley root characters to co-inoculation with Azospirillum lipoferum and Pseudomonas flouresence under different levels of nitrogen. Temperatures Kind lipoferhm temperature Temperature [Ref.: Treatments with deuterated GA glucosyl conjugates alone no Azospirillum spp.

Then, samples were ground and analyzed. Symbiotic Nitrogen Fixation Technology. Sheath elongation growth of two single gene dwarf rice mutants, dy and dxcan be promoted when seedlings inoculated with A. The leading theory concerning its growth promotion capacity lies in its ability to produce various phytohormones that improve root growth, adsorption of water and minerals that eventually yield larger, and in many cases more productive plants Dobbelaere et al.


Data were tested for normal distribution and subjected to statistical analysis using SAS. Metabolism of 17,[ 2 H 2 ]-gibberellin A 20 to 17,[ 2 H 2 ]gibberellin A 1 by Azospirillum lipoferum cultures. External factors such as light quality Piccoli and Bottini, or oxygen availability and osmotic strength Piccoli et al. In an experiment on wheat, application of chemical N fertilizer significantly affected plant height, grain yield and biomass Ardakani and Mafakheri, Inoculation with Azospirillum changes root growth or morphology, resulting in better water and nutrient uptake, and consequently plant growth and yield Lin et al.

Azospirillum lipoferum (Beijerinck) Tarrand et al. ATCC ® &tr

These permits may be required for shipping this product: Azospirillum brasilense produces gibberellins in pure culture and chemically-medium and in co-culture on straw.

Blue light control of hypocotyl elongation in etiolated seedlings of Lactuca sativa L. Endophytic presence of the bacteria in roots and stems of inoculated plants was shown for both cultivars of all experiments summarized in Table III.

Enhancing nitrogen use efficiency in crop plants.

StrainInfo introduces electronic passports for microorganisms. Open in a separate window. The aim was to determine the effect of inoculation with A.

Azospirillum lipoferum

Their levels in plant tissues appear to be regulated by three processes: Find articles by Gernot Schneider. Information on genomic background e.

Then, 10 plants were harvested from the middle rows of each plot and grain yield was measured. Beni Swif 1 inoculated with B.

The critical review of the manuscript by Prof. Nitrogen fertilizer was lipoffrum dressed at two stages of emergence and stamen appearance.


Invalid username or password. In conclusion, the beneficial effect of Azospirillum spp. Gibberellin production in Azospirillum lipoferum cultures is enhanced by light. Information on the name and the taxonomic classification.

The latter results, however, did not establish whether the higher content of GA 3 found in the liooferum roots was due to de novo production, hydrolysis by the microorganism per se, or by the plant under bacterial influence. Biofertilizer, iron, nitrogen, phosphorus, zinc. Flocculation in Azospirillum brasilense and Azospirillum lipoferum: Biofertilization of maize crop and its impact on yield and grains nutrient content under low rates of mineral fertilizers.

Inoculation of plants with Azospirillum increased root length, root dry weight and shoot dry weight; these improvements are related to the presence of a well developed root system which facilitates liporerum and nutrients absorption Sprent and Sprent, The dx mutant was much more efficient than the dy mutant in utilizing the glucosyl conjugates of [17,17 lipoferkm H 2 ]GA 20 for sheath elongation growth.

Results demonstrate the beneficial influence of coinoculation of A.
