In 2002, shading was created with winter wheat at different seeding rates. In 2003, shading was created with different shading cloths and was adjusted to the changing light intensities in differently farmed winter wheat fields. In both years, thistle seeds were sown directly into the plots. In 2002, seedling numbers in the shaded treatments were lower than in the unshaded control. In the second experimental year, seedling numbers were highest in plots with rather low light intensities. After the removal of wheat or shading cloths in August, a second peak of germination in the formerly shaded plots led to approximately equal seedling numbers in all treatments. Very low numbers of root sprouts were produced in the shaded treatments. In these treatments, biomass of sprouts and roots were also considerably reduced in both years."],["dc.identifier.isi","000225651400021"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/49338"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Eugen Ulmer Gmbh Co"],["dc.publisher.place","Stuttgart"],["dc.relation.conference","22nd German Conference on Weed Biology and Weed Control"],["dc.relation.eventlocation","Stuttgart, GERMANY"],["dc.relation.issn","0340-8159"],["dc.title","Germination and development of Cirsium arvense under competition for light - a model experiment"],["dc.type","conference_paper"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

However, plant diversity in such wild plant sowings based on seed mixtures is often low due to thehigh competitiveness of few, common species. Here we analysed whether intraspecific aggregation could enhance theperformance of less competitive species, and how plant performance is influenced by the number of species in amixture. We focused on inter- and intraspecific competition between six agricultural wild plant species (Centaureacyanus,Calendula arvensis,Melilotus officinalis,Poa annua,Bromus mollis,Medicago lupulina), and tested (i) twodifferent seeding patterns (intraspecifically aggregated vs. randomly dispersed) and (ii) three different species mixtures(monocultures, three-species, and six-species mixtures). Plant performance was measured in terms of number ofindividuals, biomass per individual, and biomass per m2. Intraspecific aggregation resulted in higher numbers ofindividuals of all species, while mixtures generated lower numbers of individuals. The performance of plant speciesdiffered depending on their position in the competitive hierarchy. Competitively weak species suffered much less fromintraspecific than interspecific competition in terms of biomass, and the competitively weakest species became evenexcluded in the most species rich and randomly dispersed sowings with high interspecific competition. In conclusion,the performance of wild plant species was influenced by both seeding pattern and number of species in a mixture.Intraspecific aggregation enabled the coexistence of competitively weak species by reducing interspecific competitiveexclusion processes. Consequently, agri-environmental schemes designed to preserve and enhance biodiversity shouldconsider small-scale processes influencing the distribution and abundance of plants, and develop new agriculturalsowing technologies to cultivate competitively weak and endangered wild plant species."],["dc.identifier.doi","10.1016/j.ppees.2009.02.001"],["dc.identifier.gro","3149893"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6602"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","1433-8319"],["dc.subject","Annuals; Biodiversity conservation; Interspecific and intraspecific competition; Seeding pattern"],["dc.title","Spatial aggregation facilitates coexistence and diversity of wild plant species in field margins"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]
