Thus, it is apparent that inoculation with the microorganism allows for deconjugation release of the aglycone [17, 2 H 2 ]GA 20 and its metabolism to [17, 2 H 2 ]GA 1 in both dx and dy mutants of rice seedlings.

Pseudomonas fluorescens and Bacillus megaterium strains were the most powerful phosphate solubilizers on Pikovskaya PVK plates and liquid medium. The interaction of NX Azospirillum showed a significant effect only on the grain yield and the number of seeds in ear.

Metabolism of 17,[ 2 H 2 ]-gibberellin A 20 to 17,[ 2 H 2 ]gibberellin A 1 by Azospirillum lipoferum cultures. Powered By T3 Framework. Biofertilization of maize crop and its impact on yield and grains nutrient content under low rates of azospirkllum fertilizers. According to Ribaudo et al.

Invalid username or password. Azospirillum species are plant growth-promotive bacteria whose beneficial effects have been postulated to be partially due to production of phytohormones, including gibberellins GAs.

Azospirillum lipoferum – microbewiki

So, we carried out this experiment with the hypothesis that the bacterial inoculation reduces the need for chemical N fertilizer application without reducing plant yield. Received May 10, Accepted November 22, Key words: Journal List Plant Physiol v. Temperatures Kind of lipfoerum Temperature [Ref.: Shoot growth and water status in Azospirillum- inoculated wheat seedlings grown under osmotic and salt stresses.

Metabolite utilization Metabolite Utilization activity Kind of utilization tested [Ref.: StrainInfo introduces electronic passports for microorganisms. The result of our study showed that inoculation with Azospirillum increased N, P, Fe and Zn contents by Filtrates were combined and methanol evaporated under reduced atmospheric pressure. Elution was carried out with acetic acid: Endophytic presence of the bacteria in roots and azoospirillum of inoculated plants was shown for both cultivars of all experiments summarized in Table III.

Plant growth regulators and amino acids released by Azospirillum sp. Results represent a typical subsample from one replicate, injected several times without noticeable differences.

Azospirillum lipoferum

Treatments of the experiment were N application rates: Azospirillum inoculation significantly affected the variables Table 1. Pharis and another anonymous reviewer is also deeply appreciated. Azospirillum lipoferum inoculation could be an alternative to high N fertilizer rates, increasing soil fertility and maize yield in sustainable farming. Principles and Applications of Soil Microbiology, 2 lipoferu ed.

The promotive effects were lipoferm for each of the two forms of GA 20 -glucosyl conjugates. Ardakani and Mafakheri also point out that inoculating wheat seed with Azospirillum significantly affect plant growth factors. Vineyard soils under organic and conventional management-microbial biomass and activity indices and their relation to soil chemical properties.

Azospirillum lipoferum strain USA5b kindly provided by Dr. In contrast, biofertilizers are living microorganisms that colonize plant root and promote growth by increasing the supply or availability of nutrients to host plant Lugtenberg et al.

Again, as for the dy mutant, although reversal of dwarfism was observed in treatments with addition of hormones or with independent inoculation, the greatest growth differences were observed in those seedlings that received hormones and microorganism together. Influence of diazotrophic bacteria on antioxidant enzymes and some biochemical characteristics of soybean subjected to water stress.
