| Abstract/Contents: | "Both acetylene reduction and colorimetric methods were employed to measure nitrogenase activity, the solubilizing phosphorus capability and secretion of plant growth hormone of 21 nitrogen-fixing bacteria strains isolated from Kentucky bluegrass rhizosphere soil samples. The result indicated that the nitrogenase activity of 21 tested nitrogen-fixing bacteria strains were between 39.9 and 227.5 nmol路mL-1路h-1.There were 14 strains (67% of all strains) whose activities were more than 100 nmol路mL-1路h-1.The solubilizing phosphorus intensity of nitrogen-fixing bacteria were between 13.38 渭g路mL-1 and 58.21 渭g路mL-1.Three of these tested strains - N4, N16 and N20 demonstrated stronger solubilizing phosphorus capability. Eight of these tested strains - N2, N4, N5, N10, N14, N16, N17 and N20 demonstrated strong ability of excreting plant growth hormone were measured." |
