Significant discoloration relationships in live oak and shumard oak in response to reduction pruning.
| Equation 6z | Depth of discoloration (live oak) = 73.8 − 1.02 branch departure angle r2 = 0.156, regression model P = 0.017 |
| Equation 7 | Area of discoloration (live oak) = 41.6 + 0.683 initial cut diameter (cm) r2 = 0.123, regression model P = 0.033 |
| Equation 8z | Area of discoloration (shumard oak) = 35.0 + 3.35 initial cut diameter (cm) r2 = 0.615, regression model P < 0.001 |
| Equation 9z | Area of discoloration (live oak) = 46.9 − 0.124 aggregated sprout base diameter r2 = 0.17, regression model P = 0.011 |
↵zConfidence intervals at α = 0.05 reject zero slope line in scatterplot.
