Other claims from this paper (8)
- Observation Embryos showed little differentiation for about five weeks.
- Observation Embryos within each seed competed until a dominant embryo survived.
- Observation Seed ripening occurred over a few weeks with little change in embryo size.
- Observation Embryos collected on the same date occupied diverse developmental stages.
- Observation Average embryo growth during differentiation was about half a stage daily.
- Association Embryo growth was slower in the smallest seeds.
- Association At shoot tip differentiation and cotyledon initiation, embryo volume related closely to endosperm and seed volumes.
- Association Seed size, embryo size, endosperm size, and cotyledon number were correlated.
