After vegetative multiplication, the 25 possible combinations of Lolium genotype x Trifolium genotype were planted in the greenhouse in order to investigate competition between the genotypes. The comparison of the five combinations whose individual components had been neighbours with the combinations of genotypes that had not coexisted before disclosed no difference in total biomass production over 7 months. However, the yield of Trifolium increased when grown with the Lolium genotype which had been its natural neighbour, while the latter showed a decrease in yield. This neighbour specificity existed even when carryover effects from the sampling site had been eliminated (preconditioning period of 18 months) and when native Rhizobium strains were not present (inoculation with a non-native strain). The complex pattern of neighbour specificity with time indicated the importance of environmental conditions for its outcome. These results are a further confirmation of positive effects on the growth of Trifolium repens when grown together with its natural neighbour. They are discussed in the context of coexistence and coevolution Springer-Verlag, 1992 Trifolium repens nationallicence Lolium perenne nationallicence Competition nationallicence Coadaptation nationallicence Evolution nationallicence Lüscher Andreas Eidgenössische Technische Hochschule, Institut für Pflanzenwissenschaften, ETH-Zentrum, 8092, Zürich, Switzerland aut Connolly John Department of Statistics, University College Dublin, 4, Dublin, Ireland aut Jacquard Pierre Centre Louis Emberger (CNRS), Route de Mende, BP 5051, 34033, Montpellier cedex, France aut Oecologia Springer-Verlag 91/3(1992-09-01), 404-409 0029-8549 91:3<404 1992 91 442 https://doi.org/10.1007/BF00317630 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/BF00317630 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Lüscher Andreas Eidgenössische Technische Hochschule, Institut für Pflanzenwissenschaften, ETH-Zentrum, 8092, Zürich, Switzerland aut NATIONALLICENCE 700 1- Connolly John Department of Statistics, University College Dublin, 4, Dublin, Ireland aut NATIONALLICENCE 700 1- Jacquard Pierre Centre Louis Emberger (CNRS), Route de Mende, BP 5051, 34033, Montpellier cedex, France aut NATIONALLICENCE 773 0- Oecologia Springer-Verlag 91/3(1992-09-01), 404-409 0029-8549 91:3<404 1992 91 442 Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
