Functional prediction of PGP traits | Fraction effecta | Rootstock effectb | |
---|---|---|---|
Root vs rhizosphere | Root (df = 4,10) | Rhizosphere (df = 4,10) | |
ACC deaminase activity | 0.291; t = 1.0937 | 0.0006; F = 12.77 | 0.0538; F = 3.380 |
Auxin production | 0.038; t = 2.141 | 0.0720; F = 3.005 | 0.3988; F = 1.123 |
Nitrogen Metabolism | 0.259; t = 1.0923 | 0.2955; F = 1.24 | 0.4616; F = 0.978 |
Phosphate solubilization | 0.235; t = 1.2452 | 0.0119; F = 5.681 | 0.3389; F = 1.286 |
General PGP (VOCs production) | 0.350; t = 0.9454 | 0.6981; F = 0.558 | 0.5278; F = 0.844 |
Siderophore synthesis | 0.296; t = 1.0649 | 0.4891; F = 0.920 | 0.6096; F = 0.699 |
aT test statistical analysis was performed to compare the functional prediction of PGP traits in the two fractions. The p and t values have been reported to evaluate statistical significance
bOne-way analysis of variance (ANOVA) was performed to evaluate the rootstock effect on the functional prediction of PGP traits in root and rhizosphere fractions. The p and F values have been reported to evaluate statistical significance
