From: Estimating heat tolerance of buds in southeastern US trees in fire-prone forests
Principal component analysis for bud percent mortality by species: A Clusters were established for (1) mockernut hickory (green dots); (2) red maple (purple dots), chestnut oak (blue dots), scarlet oak (orange dots), and yellow-poplar (brown dots); (3) American beech (red dots). B Bud length, surface area, and diameter were utilized as independent variables to generate the highest total component percentage
