Other claims from this paper (8)
- Observation Basal embryos in selfed wild and domesticated bean flowers aborted more often than stylar embryos.
- Observation Surviving basal embryos became lighter seeds than stylar embryos.
- Intervention effect Cultivar embryo survivorship was higher when maternal plants grew in larger pots.
- Observation Late abortion mortality was higher for basal than stylar embryos.
- Observation Basal embryos developed adult organs in embryo culture, indicating no gross genetic defects.
- Intervention effect More outbred cultivar crosses eliminated positional effects on embryo survival and seed size.
- Mechanism Paternal-parent differences implicated a genetic contribution to position effects.
- Association Large seeds produced larger juvenile plants than small seeds.
