Search FTB Enter search term Azospirillum species are plant growth-promotive bacteria whose beneficial effects have been postulated to be partially due to production of phytohormones, including gibberellins GAs.

The application of biofertilizers is a cost effective necessity to obtain a high quality yield and avoid environmental pollution.

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 water and nutrients absorption Sprent and Sprent, Effects of Azospirillum spp.

In most cases, there was no significant difference between the two highest doses, i.

Liipoferum Permits These permits may be required for shipping this product: This confirms earlier work by Piccoli et al. Metabolism of 17,[ 2 H 2 ]-gibberellin A 20 to 17,[ 2 H 2 ]gibberellin A 1 by Azospirillum lipoferum cultures.


Spirillum nitrogen-fixing medium Growth Conditions Temperature: Metabolite production Metabolite Production [Ref.: The hypothesis was that the bacterial inoculation decreases the need for N fertilizer application without reducing plant yield.

Azospirillum lipoferum – microbewiki

Rice seedlings had been treated with GA-A 20 -glucosyl conjugates and inoculated with Azospirillum spp. 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.

The difference in growth for inoculated versus noninoculated seedlings can best be explained as hydrolytic plus metabolic activity of the bacteria on the conjugate. The authors highly acknowledge Islamic Azad University, Tabriz Branch-Iran, for their fields and laboratories support.

In an experiment on wheat, application of chemical N fertilizer significantly affected plant height, grain yield and biomass Ardakani and Mafakheri,
