Title

ISOLATION AND IDENTIFICATION OF PSEDOMONAS FLUORECENS AND EVALUATION OF THEIR PLANT GROWTH PROMOTING PROPERTIES IN SOILS GOLESTAN PROVINCE

Pages

  251-264

Abstract

 The aim of this study was to investigate the promoting characteristics of PLANT GROWTH, PSEUDOMONAS FLUORESCENS in the soils of Golestan province. Thirty PSEUDOMONAS FLUORESCENSspecies were isolated from 45 rhizospheric soils of soybean plants and their growth promoting potentials were studied as a function of SIDROPHORE and HYDROGEN CYANIDE production rate, AUXIN and also mineral phosphate dissolution potential. The ability of production of isolates siderophore evaluated semiquantitively by CAS-Agar medium and the best isolate was P1/15 with the average ratio of halo diameter to 3.10 colone and isolates P11/1 with the zone diameter to colony 1.29 had the lowest production. The ability of HCN production of isolates evaluated by TSA medium riched by glycine and the best isolate was P1/4 with the extreme HCN production. The ability of isolates in AUXIN production also performed under condition of 0 and 50 tryptophane concentrations and P1/4 isolate with 92.01 mg/ml AUXIN production in the present of tryptophane had the highest rate of production of this hormone and isolates P5/2 to produce 2.62mg/ml had the lowest production. The isolates ability of dissolution of mineral phosphate by liquid PKV medium and P2/7 isolate with the 44.28 mg/l had the most solubility and isolates P11/1 with a solubility of 12.07 mg/l had the lowest solubility.
