Other claims from this paper (8)
- Observation Bracteal nectar production peaks on the day of anthesis and continues during fruit maturation.
- Mechanism Bracteal nectaries are interpreted as functioning in pollination and defense.
- Observation Constitutive bracteal nectar secretion exceeds foliar secretion by 80 to 110 times.
- Intervention effect Herbivore damage to leaves induces foliar nectar production.
- Intervention effect Fruit damage does not induce bracteal nectar production.
- Intervention effect Herbivory on the fruiting structure decreases bracteal nectar production.
- Observation Nectar allocation is interpreted as fitting optimal defense theory.
- Mechanism The authors argue that herbivore accessibility shapes indirect defense allocation.
