- Abstract
-
Set-up of ACi curves, N, P and LMA values for dominant species. Establish the extent to which rates of light saturated photosynthesis, Vcmax and Jmax change in response to associated traits and to climatic moisture in the Great Western Woodlands. Experimental design and methods: In April and October 2013, we surveyed ACi curves and related leaf traits (area:mass ratios, and concentrations of nitrogen and phosphorus) in 37 species growing at the Great Western Woodlands TERN - SuperSite. Leaves were sampled from different trees ranging from 1 to 4 replicates per specie. Asat(light saturated photosynthesis), Amax (CO2 saturated photosynthesis), Ci (intercellular partial pressure of CO2) and Rlight(CO2 evolution from mitochondria in the light, other than that associated with the PCO cycle) were used to calculate rates of Vcmax (maximum velocity of the carboxylase) and Jmax (maximum rate of carboxylation allowed by the electron transport). Vcmax and Jmax were corrected for temperature.

ACi curves
Our primary measured response variables were ACi curves (using a program in Licor 6400 gas exchange systems) setting the mixer CO2 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 mol photons m-2 s-1. Dark respiration (Rdark) was measured after turning off the light source for 10 minutes.
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.
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 measured on 1 to 4 trees from each study species.
These measurements provided data on Asat (light saturated photosynthesis), Amax (light saturated photosynthesis and at saturating atmospheric CO2 concentration), stomatal conductance (Gs), Internal CO2 concentration (Ci), Rdark. Maximum velocity of the carboxylase (Vcmax), maximum rate of carboxylation allowed by the electron transport (Jmax) and CO2 evolution from mitochondria in the light, other than that associated with the PCO cycle (Rlight) were calculated from Farquhar model and also Bernacchi correction for temperature.
