PLANT GROWTH PROMOTIONAL STUDIES OF PHYLLOSPHERIC IAA PRODUCING BACTERIA AND EVALUATION OF THEIR AUXIN PRODUCING POTENTIAL THROUGH FTIR

Abstract

This research examined how phyllospheric bacteria improve Triticum aestivum growth. Auxin production and plant growth in regulated lab settings and wire homes were the major goals of this research on phyllospheric bacteria. It was tested if known phyllospheric bacterial strains could produce auxin with or without L- tryptophan. The phytostimulatory impact on Triticum aestivum was examined in axenic and wire house environments. Based on auxin production, twelve bacterial varieties were selected (E1, E2, E3, E4, E5, E6, E7, E8, E9, E10, E11, and E12). Colorimetric studies and Fourier transform infrared spectroscopy verified auxin synthesis. These phyllospheric bacteria produced different auxin levels. When tryptophan was added to bacterial growth, auxin synthesis increased. Many growth assays demonstrate that most inoculations provide large improvements. In wirehouses, soils E4 and E6 help plants grow best. E4 and E6 are 99% identical to Bacillus thuringiensis and Lysinibacillus fusiformis, respectively, according on 16S rDNA study. Thus, phyllospheric bacteria that produce auxin may be useful in farming.
