Other claims from this paper (9)
- Observation Ants were attracted by extrafloral nectar.
- Observation Nectar was secreted at around 80% concentration from outer-tepal nectaries.
- Observation Nectaries lacked specialized nectariferous tissue.
- Mechanism The exudate was probably secreted through two stomatal types.
- Observation Sugars and amino acids were detected in nectar.
- Observation Alkaloids, reducing acids, proteins, phenols and lipids were absent from nectar.
- Observation Nectar amino acid concentration ranged from 121.3 to 975 μg/mL.
- Observation Sucrose concentration was 97.2–100% in all species.
- Observation Glucose and fructose were absent or at 0.4–1.5%.
