Table 2.
Association between concentration of pyoluteorin (PLT) and culture conditions of P. protegens (strain DSMZ 13134). The c statistics and its p-value are reported for each of the factors tested for their association with the response variable. Multiple values of c marked by a numeric index in subscript refer to subsequent splits of the tree model. Significant c values (p < 0.05) are indicated by the symbol *.
| Response Variable | Incubation Temperature | Culture Medium | Incubation Period | Co-Culture Type |
|---|---|---|---|---|
| Concentration of PLT produced by monocultures of P. protegens (strain DSMZ 13134) | c = 0.542 | c = 2.132 | c = 1.985 | - |
| p = 0.987 | p = 0.718 | p = 0.405 | - | |
| Concentration of PLT produced by co-cultures of P. protegens (strain DSMZ 13134) and Heterobasidion spp. | c1= 33.35 * | - | - | c1 = 0.626 |
| p1 = 1.142 × 10−7 | - | - | p1 = 0.988 | |
| c2 = 10.078 * | - | - | c2 = 4.754 | |
| p2 = 2.999 × 10−3 | - | - | p2 = 0.345 |
