Table 5. Simple linear regression statistics from a model fitting back-transformed genetic-based population variation in MLD damage (percentage of juvenile leaf area) at the TEM06 trial as the response variable and latitude, elevation above sea level, mean daily maximum temperature, mean summer rainfall, mean autumn rainfall and predicted MLD risk as explanatory variables (standard errors are in parentheses).
| Explanatory variable | Intercept | Slope | R2 |
|---|---|---|---|
| Latitude (° South) | 44.58 (10.46)** | 1.42 (0.26)*** | 0.73 |
| Elevation (m × 103) | 11.98 (1.40)*** | 625 (640)NS | 0.08 |
| Daily maximum temperature (°C) | 49.52 (8.38)*** | −2.24 (0.51)** | 0.63 |
| Summer rainfall (m) | 8.22 (3.48)* | 25.15 (17.57)NS | 0.16 |
| Autumn rainfall (m) | 12.08 (3.38)** | 3.91 (12.82)NS | 0.01 |
| Predicted MLD risk (Ecoclimatic Index) | 21.30 (3.12)*** | −0.319 (0.118)* | 0.40 |
