Does root competition asymmetry increase with water availability

摘要: Background: Below-ground competition as a major structuring force in plant communities can be either symmetric or asymmetric with important consequences for the coexistence of plants. It is matter controversy whether asymmetry increases resource availability not. Aims: This study tested hypotheses that root between mature Fagus sylvatica and Quercus petraea trees more pronounced non-water-limited environments. Methods : Initially equal-sized tree fine roots were grown 365–390 days growth chambers situ exposed to by conspecific an allospecific root. Relative rate was used determine competition. Different soil moisture regimes considered conducting throughfall reduction experiment including data from earlier experiments contrasting regimes. Results: The competitive interaction asym...
