Other claims from this paper (7)
- Intervention effect Defoliation increased photosynthesis of fully expanded Acacia leaves markedly.
- Intervention effect Light defoliation produced the greatest rise in photosynthetic rate.
- Intervention effect Total nonstructural carbohydrate levels fell significantly after defoliation.
- Intervention effect Carbohydrate levels recovered faster after heavy than light defoliation.
- Intervention effect Carbohydrate recovery was faster after second-half than first-half growing-season defoliation.
- Observation Acacia heavily defoliated in the second half of the growing season had not fully recovered carbohydrate levels by late-autumn leaf fall.
- Intervention effect Moisture stress affected carbohydrate levels much less than defoliation.
