Konkurrenzdruck und Zuwachs von Pinus radiata

Abstract

Die Abhangigkeitsbeziehung zwischen drei Konkurrenzvariablen und dem Volumenzuwachs vonP. radiata wurde untersucht, namlichProdan-Ehrlenspiels n-Baum-Stichprobe (Bantrei), eine Abwandlung vonSpurrs Modifikation der Winkelzahlprobe (bangtreei) undKennels Abstandsvariable (distreei). Die Ergebnisse waren folgende: 1. In den undurchforsteten A-Flachen ergabbangtreei die hochste Regressionsquadratsumme, in den stark durchforsteten C-Flachen dagegendistreei. 2. Die Regressionsquadratsumme ist vom Wert des Index i abhangig. 3. Fur dieselbe Baumhohe und denselben Wert der Konkurrenzvariablenbangtree4 ist der Zuwachs in stark durchforsteten Bestanden groser als in schwach durchforsteten.
