Apical shoot scoring system for apical shoot's architecture. (International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests, 2010)
Link to this table.
|Score and class||Definition||Remark|
|Class 1: Exploratory phase||Apical shoots and upper side buds form long shoots||Flat, longitudinal expansive shoot development|
|Class 2: Intermediary||Intermediary between class 1 and class 3|
|Class 3: Degeneration phase||Only apical bud forms a long shoot. Shoots of side buds are stunted.||Spear-shaped development of main shoots and reduced side shoot formation|
|Class 4: Intermediary||Intermediary between class 3 and 5|
|Class 5: Stagnation phase||Stunted long shoots||Claw-like appearance because of pluriannual short shoot chains|
|Class 6: Intermediary||Intermediary between class 5 and class 7|
|Class 7: Resignation phase||Die-back of twigs of the topmost part of the crown or even the whole crown itself|
|Class 8: Regeneration phase||Phase with obvious regeneration||From worse phase to a better form on the same branch|
