e0“Fruit‐specific fertilization and developmental conditions seem to be the main factors driving the fruit abortion rate and seed mass, causing high variability in seed survival and mass within maternal trees.”

Other claims from this paper (6)
- Observation Seed abortion rates were overdispersed per fruit within trees in all populations.
- Association Abortion was more frequent at the extreme positions of fruit in all populations.
- Observation The abortion patterns were present from the beginning of fruit formation.
- Association Stylar ovules did not have higher survival despite earlier fertilization.
- Association Abortion events were negatively related to seed mass.
- Mechanism The authors suggest the abortion–mass correlation may reflect the fruit’s capacity to drain maternal resources.
