  1. Response of root biomass and plant leaf area to soil-nitrogen for two weed species (rapeseed and Vulpia) cultivated either in RhizoTubes or pots was assessed by the ratio of the trait value at high soil-nitrogen to the trait value at low soil-nitrogen (mean value ± S.E., n = 5). Trait values were measured 51 days after sowing. Plant leaves and roots were separated and their biomasses were measured as in “Methods”. Leaf area was measured with a leaf area meter. Different capital letters in parentheses indicate significant differences between traits measured in RhizoTube or in pot for P < 0.05 (*)
