Table 1.
Design of the experimental setup, representing the number of microcosms assigned to each combination of richness level of barley genotypes (X, Y, and Z) and AMF species (A, B, and C).
| AMF richness | ||||||||
|---|---|---|---|---|---|---|---|---|
| A | B | C | AB | AC | BC | ABC | ||
| Barley richness | X | 1 | 1 | 1 | 1 | 1 | 1 | 3 |
| Y | 1 | 1 | 1 | 1 | 1 | 1 | 3 | |
| Z | 1 | 1 | 1 | 1 | 1 | 1 | 3 | |
| XY | 1 | 1 | 1 | 1 | 1 | 1 | 3 | |
| XZ | 1 | 1 | 1 | 1 | 1 | 1 | 3 | |
| YZ | 1 | 1 | 1 | 1 | 1 | 1 | 3 | |
| XYZ | 3 | 3 | 3 | 3 | 3 | 3 | 9 | |
Blocks of the same richness level included always nine microcosms and are indicated by numbers. The presented setup was replicated for drought and ambient treatments.
