Associative Symbiosis

The influence of plant growth regulator triman-1 on nitrogen fixing bacteria and nitrogen fixation process in barley root zone was studied in the laboratory and field conditions. It was shown that triman- 1 enhances associative nitrogen fixation activity when mineral nitrogen fertilizers (N30) was used. The use of triman-1 increases efficiency of associative symbiosis more effectively with the use of carboammonium salts rather than with ammonium nitrate.

Percentage Incidence

Acid- and gas-producing nitrogen-fixing bacteria associated with rice roots and leaf sheaths were isolated. These isolates along with reference enterobacteria strains were characterized biochemically and serologically. Using selected cultural and biochemical tests, all isolates from rice were identified as Enterobacter cloacae, except two strains which were found similar to Klebsiella pneumoniae. However, further biochemical tests showed that the Klebsiella isolates were K. planticola. Antisera and fluorescent antibodies (FA) were prepared against K. pneumoniae M5a1, K. planticola DWUL2, and E. cloacae EnSs. The results of FA cross-reactions of 28 strains isolated from rice plants and of other type cultures showed a separation into two different serogroups: E. cloacae and K. planticola. However, the cross-reactions in gel immunodiffusion were found to be extensive and widespread. All strains of Enterobacteriaceae tested produced at least one immunodiffusible precipitin band with any one or all antisera. The population of N2-fixing enterobacteria associated with the root and stem of rice fell within the range of 103 and 105 per gram dry weight. The percentage incidence of N2-fixing enterobacteria among the aerobic heterotrophic bacteria in the root and stem was found to be less than 1%.

Abstract The research aims is to determine the suitability of nitrogen fixing bacteria, namely Actinomycetes, Azospirillum and Azotobacter with upland rice seeds to the speed of radicle formation and growth of upland rice plants. Upland rice plant growth measurement parameters include; speed of formation of radicle length, upland rice plant height, number of upland rice tillers, dry weight of the top of upland rice plants and roots of upland rice plants, wet weight of upland rice plants and roots of upland rice plants, and total N of upland rice plants and upland roots Testing the application of N2 fixing bacteria on upland rice plants on a laboratory scale was carried out to determine the suitability of microbes with upland rice plant seeds in vitro. The pot test was carried out to determine the suitability of the N2 fixing bacteria with the vegetative growth of upland rice plants in vivo. Data were analyzed using ANOVA with Duncan’s advanced test. The results showed that upland rice plants inoculated with Actinomycetes, Azospirillum and Azotobacter showed significantly different growth from upland rice plants without nitrogen fixing bacteria treatment, namely the radicle formation speed and radicle length, plant height, number of tillers, wet weight, dry weight, and total N (%) plants. It can be concluded that the inoculation of nitrogen-fixing bacteria on upland rice plants has a significant effect on plant vegetative growth parameters and plant nitrogen content.
