Title

ISOLATION AND IDENTIFICATION OF AZOTOBACTER SPP AND EVALUATION OF THEIR PLANT GROWTH PROMOTING PROPERTIES

Pages

  121-135

Abstract

 AZOTOBACTER is an important bacteria in crop rhizosphere. This research aimed the isolation of local AZOTOBACTER under cultivation of soybean plant in Golestan province and their potential growth promoting-ability. After identification of 30 isolates their ability to molecular NITROGEN FIXATION were tested with Acetylene to Ethylene reduction method. Their ability in AUXIN production and solubilizing the mineral P were tested with colorimetric method and sidrephore production potential was tested with Cas-agar medium. The maximum NITROGEN FIXATION was in Az26 (428.23 nm.vial.h-1 ethylene) and minimum in Az27 (21.39 nm.vial.h-1 ethylene). AUXIN production was highest in Az4 isolate (27.3 mg/l) and lowest in Az20 isolate (0.0157 mg/l). Also maximum sidrephore production was in Az9 and minimum in Az18 observed with diameter halo on colony of 6.36 and 2.24 in 72 hours respectively.
