Effect of different environments on the relative survival of P. fluorescens SBW25EeZY-6KX in a mixture of SBW25 variantsa
| No. of days after inoculation | % and logit % of P. fluorescens SBW25EeZY-6KX in a mixture of SBW25 variants in:

||
|---|---|---|---|
| Pea rhizosphere | Wheat rhizosphere | Soil | |
| 0 | 26.7 (−1.11) | 23.7 (−1.21) | 24.9 (−1.11) a |
| 14 | 26.9 (−1.01) | 14.3 (−2.02) | 5.6 (−2.84) b |

a
The mixtures contained SBW25-6K, SBW25-6KX, and SBW25EeZY-6KX in equal proportions. Variant mixtures were applied either to the seed or as a soil drench (n = 4). Data are expressed as the percentage of SBW25EeZY-6KX in the total population of SBW25 variants and as logit transformation of the percentage data (in parentheses). Significant (P < 0.05) differences between two treatments were obtained by LSD analyses and are indicated by different letters. The overall significance for soil was <0.001; the data for the rhizospheres were not significant.
