Other claims from this paper (12)
- Association Reproductive biomass allocation in Centaurea cyanus varied with plant size.
- Association Reproductive and vegetative mass had a close to linear relationship.
- Method / resource The linear size dependent reproductive output model worked well across size differences from competition, nutrient supply, and density.
- Association The vegetative to reproductive biomass relationship differed significantly across population density and fertility levels.
- Intervention effect mineral fertiliser increased generative flowerhead biomass.
- Intervention effect manure increased generative flowerhead biomass.
- Intervention effect mineral fertiliser decreased reproductive effort.
- Intervention effect manure decreased reproductive effort.
- Association Generative dry weight increased more rapidly with plant size at higher population density.
- Association Generative dry weight increased more rapidly with plant size at lower fertility.
- Association Seed production was not directly dependent on total reproductive structure biomass.
- Association At low nutrient supply, C. cyanus produced more offspring per gram biomass.
