  1. Due to the different germination times and growth rates, the age of the plant individuals when being transplanted in the experiments differs between species. e.g., B. erectus was transplanted at the age of 2 weeks. In this case, herbicide treatment in the simulated monoculture started 2 weeks after germination and initial biomasses in the community setup are based on these biomasses (biomasses 2 weeks after germination in the simulated monocultures). In the analyses of B. erectus in the monoculture, the simulated biomasses of plants 4, 6 and 8 weeks after germination are equivalent to the biomass measurements of week 2, 4 and 6 in the experiments
  2. aBBCH12-14 is reached between 2 and 3 weeks
