|---|---|---|---|---|---|---|
| t | r | P-value | t | r | P-value | |
| Light | –23·60 | 0·65 | 0·001 | –8·78 | 0·30 | 0·001 |
| Moisture | –24·61 | 0·66 | 0·001 | –15·85 | 0·49 | 0·001 |
| Nitrogen | 4·25 | 0·15 | 0·001 | 0·68 | 0·03 | 0·495 |
The mean log seed mass and embryo to seed size ratio (E:S) in each plot are dependent variables, and the mean Ellenberg indicator values for light, soil moisture and nitrogen calculated for separate plots are predictor variables.
