Other claims from this paper (15)
- Observation G. rivale occupied wetter and less shaded habitats than G. urbanum.
- Observation G. rivale population differences mainly involved leaf size and stature.
- Observation G. urbanum population variation mainly involved growth rates.
- Observation The two Geum species responded differently to waterlogging.
- Observation Within species, waterlogging tolerance varied only slightly.
- Observation Hybrid progeny responded to waterlogging like one or the other parent species.
- Intervention effect Waterlogging slightly raised shoot to root dry weight ratio in tolerant families.
- Intervention effect Waterlogging strongly raised shoot to root ratio in G. urbanum and less tolerant families.
- Intervention effect Waterlogging strongly reduced root dry weight in G. urbanum and less tolerant families.
- Observation Tolerant families showed pronounced axillary bud proliferation and a rhizome like caudex.
- Observation Less tolerant families and G. urbanum lacked a caudex and had reduced axillary bud proliferation.
- Observation Many tolerance associated traits were highly heritable in hybrids.
- Observation Drained to flooded ratios for root dry weight, shoot to root ratio and specific leaf area differed heritably among hybrids.
- Observation Families maternally resembling G. rivale were always relatively waterlogging tolerant, while some resembling G. urbanum were tolerant.
- Observation Authors inferred waterlogging chiefly affected roots, with shoot growth and development also affected.
