TABLE 2.
Nitrogen fixation by symbioses of A. indica and B. denitrificans (LMG 8443) compared to two other strains isolated from nodules of this host legumea
| Strain | Plant dry wt (mg/plant) | Total plant nitrogen (mg/plant) | Acetylene reductionb (μmol of CH2H4/plant) |
|---|---|---|---|
| LMG 8443 | 302 A | 11.7 A | 11.5 A |
| USDA 4424 | 299 A | 11.1 A | 4.7 B |
| BTAi1 | 241 B | 7.3 B | 6.5 B |
| Control | 44 C | 0.4 C | 0 C |
Values in the same column flanked by the same capital letter are not significantly different at the 5% level of probability as determined by Duncan's new multiple range test.
That is, nitrogenase activity.
