Measured leaf dark respiratory CO -release is not controlled by stomatal conductance.

Leaf dark respiratory CO -release (R ) is, according to some literature, dependent on the rate of leaf transpiration. If this is true, then at a given vapor pressure deficit, the leaf stomatal conductance (g ) will be expected to be a controlling factor of measured R at any given time. We artificially lowered leaf g by applying abscisic acid (ABA).

Application of the thermal death time model in predicting thermal damage accumulation in plants.

The thermal death time (TDT) model suggests that the duration for which an organism can tolerate thermal stress decreases exponentially as the intensity of the temperature becomes more extreme. This model has been used to predict damage accumulation in ectothermic animals and plants under fluctuating thermal conditions. However, the critical assumption of the TDT model, which is additive damage accumulation, remains unverified for plants.

Consistent diurnal pattern of leaf respiration in the light among contrasting species and climates.

Leaf daytime respiration (leaf respiration in the light, R ) is often assumed to constitute a fixed fraction of leaf dark respiration (R ) (i.e. a fixed light inhibition of respiration (R )) and vary diurnally due to temperature fluctuations.
