Abstract: 

Arabidopsis thaliana-populations were taken from the seed bank of habitats of different land-use regimes in Hessen (Lahn-Dill-Region). Germinated plants were selfed to produce individuals of the F1-generation for analysis. We tested whether reproductive and genetic traits of individuals differed among four land-use regimes. As reproductive traits we analysed seed weight (of 1000 seeds) and germination rate at different temperatures. Genetic diversity was estimated using AFLP markers and the intraspecific population structure was analysed by microsatellites.
We found differences between individuals originating from habitats of the different land-use regimes with respect to reproductive and genetic traits. Especially populations from intensively used crop fields differed from those of the other habitats studied. The former were characterized by lower seed weight, a higher germination rate and a lower heterozygosity. Our results indicate that land-use regimes may be important driving forces with an impact on reproductive traits as well as on genetic diversity of A. thaliana.
