Other claims from this paper (11)
- Intervention effect Citric acid stimulated about 50% more resin release.
- Intervention effect Ethrel yielded resin amounts similar to traditional paste.
- Intervention effect Salicylic acid yielded resin amounts similar to traditional paste.
- Intervention effect All stimulants reduced seedling growth.
- Intervention effect Midday water potential did not differ significantly among stimulants.
- Intervention effect Stomatal conductance did not differ significantly among stimulants.
- Association Internal resin accumulation correlated strongly with total resin production.
- Association Resin canal density correlated strongly with total resin production.
- Intervention effect More-acidic pastes tended to cause xylem damage.
- Intervention effect More-acidic pastes tended to cause resin retention.
- Mechanism The authors suggest that moderate acidity suffices to trigger resin biosynthesis and release.
