Abstract

HERNANDEZ-MENDOZA, José Luis et al. The effect of different anthranilic acid concentrations on maize growth. Rev. colomb. biotecnol [online]. 2010, vol.12, n.1, pp.57-63. ISSN 0123-3475.

The plant growth-promoting ability of the Azospirillum brasilense rhizo-bacterium is based on auxin production and that of other hormones, anthranilic acid (AA) being outstanding amongst them. This work was thus aimed at determining the effects of anthranilic acid (0, 500, 1000, 3000, and 5000 ppm) on maize growth and dry biomass accumulation in greenhouse conditions using the 83G66 hybrid. Significantly increased plant growth (leaf area and plant height) was achieved with 500 to 3,000 ppm AA, whilst 1,000 to 3,000 ppm AA significantly increased dry biomass accumulation in maize compared to control (0 ppm). 90% of AA in maize plants was assimilated during the first 10 days post-treatment

Keywords : Auxin; phyto-hormone; plant growth-promoting rhizobacteria; Zea mays L.
