Other claims from this paper (10)
- Intervention effect Lower light significantly decreased germination in both Bidens species.
- Intervention effect Lower light significantly decreased root and shoot biomass in both Bidens species.
- Intervention effect Lower light significantly increased leaf biomass in both Bidens species.
- Observation At the same light intensity, B. pilosa had higher leaf mass ratio, leaf area and relative growth rate than B. bipinnata.
- Observation At the same light intensity, B. pilosa had higher photosynthesis rate, saturation point and compensation point than B. bipinnata.
- Observation At the same light intensity, B. pilosa had higher dark respiration than B. bipinnata.
- Observation At the same light intensity, B. pilosa had lower root and stem mass ratios and root-to-crown ratio than B. bipinnata.
- Observation The authors inferred greater competitive ability of B. pilosa from its photosynthetic response to variable light.
- Observation B. pilosa showed greater physiological and morphological adaptation to different light intensities.
- Mechanism The authors inferred that B. pilosa adaptation facilitates further invasion.
