- Statement
- 1) Light response curves (AI): The primary measured response variables were AI curves (using a program in LI-COR 6400 gas exchange systems). A series of light levels were used in the light response curves starting from 1800 µmol photon m<sup>-2</sup> s<sup>-1</sup> and gradually decreased to 0 via 1500, 100, 95, 90, 85, 80, 75, 70, 65, 60, 55, 50, 45, 40, 35, 30, 25, 20, 15, 10, 5, µmol photon m<sup>-2</sup> s<sup>-1</sup> at 400ppm CO<sub>2</sub>. Each light level was applied for minimum of 60 seconds and maximum of 120 seconds using an auto-program. Dark respiration (R<sub>dark</sub>) was measured after turning off the light source for 10 minutes.<br></br> Measurements were made in field on detached branches with the xylem immediately re-cut under water. Leaves were stored with wet tissue and transported to the laboratory in the afternoon where leaf fresh mass and area were determined – thereafter, leaves were oven dried/weighed and then shipped to Canberra for chemical analysis. Measurements were made on species for which were sufficient replicates and for which removal of short branches containing several fully expanded leaves would not have an adverse effect on the growth/health of individual trees. Measurements were made on 1 to 4 trees from each study species. These measurements provided data on A1800 (light saturated photosynthesis), stomatal conductance (g<sub>s</sub>), Internal CO<sub>2</sub> concentration (C<sub>i</sub>), and R<sub>dark</sub>. CO<sub>2</sub> evolution from mitochondria in the light, other than that associated with the PCO cycle (R<sub>light</sub>) was calculated from the Kok method. <br></br> 2) ACi Curves: Our primary measured response variables were AC<sub>i</sub> curves (using a program in Licor 6400 gas exchange systems) setting the mixer CO<sub>2</sub> to 400, 300, 200, 150, 125, 100, 75, 50, 25, 400, 400, 600, 900, 1250, 1500, 1750, 2000 ppm every 3 minutes and the light saturated at 1800 µmol photons m<sup>-2</sup> s<sup>-1</sup>. Dark respiration (R<sub>dark</sub>) was measured after turning off the light source for 10 minutes.<br></br> In most cases, measurements were made in field on detached branches with the xylem immediately re-cut under water. Leaves were stored with wet tissue and transported to the laboratory in the afternoon where leaf fresh mass and area were determined; thereafter, leaves were oven dried/weighed and then shipped to Canberra for chemical analysis. In addition to the above work on detached branches, we used an additional 3 days of aerial platform access to allow in-situ measurements of different day temperatures for 9:30AM, 10:30AM, 11:30AM, 12:30PM, 13:30PM, 14:30PM, 15:30PM. Measurements were made on species for which were sufficient replicates and for which removal of short branches containing several fully expanded leaves would not have an adverse effect on the growth/health of individual trees. Measurements were made on 1 to 4 trees from each study species. These measurements provided data on A<sub>sat</sub> (light saturated photosynthesis), A<sub>max</sub> (light saturated photosynthesis and at saturating atmospheric CO<sub>2</sub> concentration), stomatal conductance (g<sub>s</sub>), Internal CO<sub>2</sub> concentration (C<sub>i</sub>), and R<sub>dark</sub>. Maximum velocity of the carboxylase (V<sub>cmax</sub>), maximum rate of carboxylation allowed by the electron transport (J<sub>max</sub>) and CO<sub>2</sub> evolution from mitochondria in the light, other than that associated with the PCO cycle (R<sub>light</sub>) were calculated from Farquhar model and also Bernacchi correction for temperature.
