Interspecific competition from undergrowth and its importance for density : – A study on the impact of undergrowth from a field trial. (English)
Abstract [en]

This study is based on a field trial at SLU in Alnarp. The idea behind the study was to see how interspecific competition influence density and annual rings on oaks (Quercus robur). The trial started out from four blocks with four different treatments. Those treatments that were initiated was: no competition, competition with herbs, competition with bushes and competition with herbs + bushes. Test samples from stumps were taken, with help from a hand saw. A total of nine samples were collected and divided on the four blocks with different competition types. With help from x-ray analysis, density and width for individual annual rings with distributed spring- and summerwood, each sample could be analyzed. The result of the study displayed that density and annual rings are affected by interspecific competition depending on type of competing vegetation. Herbs had a slight impact on annual rings, density and share of summerwood, while bushes had the biggest effect. Through the study measurements between different types of competitions it was possible to construe most effect on annual rings and share of summerwood but relatively small effect on density.
