REML estimates of variance and fixed effects parameters
| Source | ||
|---|---|---|
| Variance components | Estimate | p-value |
| Site x year | 0 | - |
| Genotype x site x year | 0.02 | 0.0005 |
| Stress x site x year | 0.11 | 0.003 |
| Non-stress | 0.02 | <.0001 |
| Moderate stress | 0.08 | <.0001 |
| Severe stress | 0.18 | <.0001 |
| Fixed effect parameters | F- statistic | p-value |
| Genotype | 3.16 | <.0001 |
| Stress | 17.93 | 0.0007 |
| Stress x genotype | 1.95 | <.0001 |
The model shows separate variances for error for each stress level.
