Effect of Inoculation Exogenous Microorganisms on Ophiopogon activities

Abstract:

Two bacteria strains (Azotobacter strain N1, Bacillus strains B1) were isolated from the soil and purified. Then they were inoculated onto the root of Ophiopogon plant.After that the oxide dismutase (SOD) and peroxidase activities of the plant were determined as well as chlorophyll content. Through comparative analysis, the result showed that after inoculation of exogenous microorganisms both the two enzyme activities and the chlorophyll content of Ophiopogon increased significantly. And these changes are enhanced with the addition of the microbial biomass. Meanwhile the mixed cultures of two bacteria strains showed a greater impact in the increase of two enzyme activities and the chlorophyll content than each single strain culture. In conclusion the inoculation of exogenous microorganisms can improve the physiological metabolism of Ophiopogon and its enzyme activity.
