Other claims from this paper (9)
- Intervention effect Girdling intensity caused no consistent or strong leaf carbohydrate response.
- Intervention effect Glucose and fructose increased slightly by 3.4% per quarter girdle in all species.
- Intervention effect Total carbon content increased 5.4% per quarter girdle in one species.
- Intervention effect Leaf mass per area increased 5.5% per quarter girdle in one species.
- Intervention effect Full girdling lowered photosynthesis in three of four species by 59-69%.
- Association The photosynthesis decrease was unrelated to increased glucose and fructose.
- Intervention effect Girdling did not affect respiration.
- Intervention effect Three-quarter phloem removal did not alter carbohydrates, photosynthesis, or respiration in three species.
- Recommendation Authors recommend avoiding girdling for carbohydrate-regulation studies.
