Abstract
During one year, the evolution of eleven groups of micro-organisms has been monitored in the soil in a plantation of oakwood (Quercus robur, the autochthonous tree species) and three alien trees (Acacia melanoxylon, Eucalyptus globulus and Pinus radiata). The main differences could be attributed to the different water regimes and soil pH, but also to some extent to the allelochemicals released. Also, the effect of the litter decomposing in the soils on germination and seedling growth was studied. The results are compatible with Rabotnov’s hypothesis, that is, that allelopathy is mainly possible between plants that have not coevolved or in special conditions where Phytotoxins are accumulated. The results are discussed regarding to this hypothesis.
