Other claims from this paper (19)
- Observation In full sunlight and 50% shade, carbon assimilation was higher in C. arabica than C. canephora.
- Observation At 80% shade, carbon assimilation did not differ between the two coffee species.
- Intervention effect Carbon assimilation of C. arabica at 80% shade was 0.49 of its full-sunlight rate.
- Intervention effect Carbon assimilation of C. canephora at 80% shade was 0.58 of its full-sunlight rate.
- Intervention effect Assimilation did not differ significantly between full sunlight and 50% shade for either coffee species.
- Association Stomatal conductance increased with irradiance in C. arabica.
- Observation The conductance increase was less evident than the assimilation increase in C. arabica.
- Intervention effect Intrinsic water-use efficiency was greater in sunlight and 50% shade than 80% shade.
- Intervention effect Irradiance did not affect stomatal conductance in C. canephora.
- Observation C. canephora had a lower A/g ratio than C. arabica under the same irradiance.
- Intervention effect Leaf carbon isotope discrimination was lower in sunlight than 80% shade for both species.
- Intervention effect Leaf carbon isotope discrimination did not differ between sunlight and 50% shade.
- Association In C. arabica, reduced Δ was associated with a 106% assimilation increase.
- Association In C. arabica, reduced Δ was associated with a 54% conductance increase.
- Association In C. canephora, reduced Δ was associated with a 73% assimilation increase.
- Association Leaf Δ was negatively correlated with instantaneous carbon assimilation.
- Association Leaf Δ was negatively correlated with stomatal conductance.
- Association Leaf nitrogen increased with irradiance and was strongly correlated with assimilation.
- Association Leaf nitrogen increase was negatively correlated with Δ.
