Temperature responses of substrate carbon conversion efficiencies and growth rates of plant tissues.
Open accessAbstract
Growth rates of plant tissues depend on both the respiration rate and the efficiency with which carbon is incorporated into new structural biomass. Calorespirometric measurement of respiratory heat and CO 2 rates, from which both efficiency and growth rate can be calculated, is a well established method for determining the effects of rapid temperature changes on the respiratory and growth properties of plant tissues. The effect of the alternative oxidase/cytochrome oxidase activity ratio on efficiency is calculated from first principles. Data on the temperature dependence of the substrate carbon conversion efficiency are tabulated. These data show that ε is maximum and approximately constant through the optimum growth temperature range and decreases rapidly as temperatures approach temperature limits to growth. The width of the maximum and the slopes of decreasing ε at high and low temperatures vary greatly with species, cultivars and accessions.

Combining respiratory heat and CO2 rates as a function of temperature enables calculation of carbon use efficiency and growth rate as functions of temperature to select the temperature range to which plants are well-adapted.
“Combining respiratory heat and CO2 rates as a function of temperature enables the calculation of carbon use efficiency (the fraction of carbon substrate incorporated into structural biomass, + ) and growth rate as functions of temperature to select the temperature range to which plants are well-adapted (Hansen et al., 2009).”

Stressful conditions such as extreme temperatures lead to changes in metabolic pathways that are reflected in high values of Rq/RCO2 and low values of +.
“Stressful conditions, due for example, to extreme temperatures, lead to the changes in metabolic pathways, which are reflected in high values of R q /R CO 2 and low values of + (Rank et al., 1991; Hansen et al., 2009).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
