Other claims from this paper (7)
- Observation Peripheral Asteraceae achenes are persistent, large, dormant and sensitive to environmental factors, whereas central ones disperse and lack dormancy.
- Observation Hedypnois cretica seedlings from dimorphic seeds differ at 40 days but not at 70 days.
- Observation Atriplex Sagittata seedlings from dimorphic seeds differ throughout the life cycle.
- Observation Both seedling types produce dimorphic seeds in the next generation.
- Observation Water, salt, nutrient and density stress change the ratio of dimorphic seeds.
- Observation Seed dimorphism is described as a quantitative trait controlled by more than two loci.
- Observation Dimorphic seeds from individuals of one species vary in morphology, dormancy, stress response, early growth and genetics.
