Other claims from this paper (8)
- Observation Severe intraspecific competition affected plant growth from early stages.
- Association An eight-fold density difference produced no significant difference in pot dry weight by 16 weeks.
- Association Higher density significantly decreased per-plant dry weight accumulation.
- Association Rhizome and inflorescence dry weight allocation increased over time at all densities.
- Association Low-density plants allocated more dry weight to inflorescences than higher-density plants.
- Association Rhizome resource allocation did not vary with density.
- Observation Plants at both lowest and highest densities allocated about one fifth of dry weight to rhizomes.
- Association Highest density stress significantly reduced tiller number and tiller dry weights per pot and plant.
