Applied Sciences, 2021 Use of leaf gas exchange measurement enhances the characterization of growth, yield, physiology, and abiotic stress response in grapevines. Accuracy of a crop response model depends upon sample size, which is often limited due to the prolonged time ...

The Impact of Phloem Feeding Insects on Leaf Ecophysiology Varies With Leaf Age
Frontiers in Plant Science, 2021 Herbivore insects have strong impacts on leaf gas exchange when feeding on the plant. Leaf age also drives leaf gas exchanges but the interaction of leaf age and phloem herbivory has been largely underexplored. We investigated the amplitude and direction

Effects of stomata clustering on leaf gas exchange [PDF]
New Phytologist, 2015 Summary A general theoretical framework for quantifying the stomatal clustering effects on leaf gaseous diffusive conductance was developed and tested. The theory accounts for stomatal spacing and interactions among ‘gaseous concentration shells’. The theory was tested using the unique measurements of Dow et al.

Repeated Mechanical Stress from Leaf Cuvette Influences Leaf Gas Exchange [PDF]
HortScience, 1992 Long-term effects on stomatal conductance of mechanical stress from repeated clamping of a porometer leaf cuvette to laminae of avocado (Persea americana Miller), carambola (Averrhoa carambolu L.), hibiscus (Hibiscus rosa-sinensis L.), mango (Mangifera indica L.), and sugar apple (Annona squamosa L.) plants were determined under glasshouse conditions ...

Journal of Environmental Engineering and Landscape Management, 2022 When temperature in the leaf gas exchange system changes, the thermodynamic parameters describing the condition of moist air also change. A temperature change of 1 oC in plant leaf tissues leads to a change in partial water vapour pressure of 144 Pa in ...

Leaf scale quantification of the effect of photosynthetic gas exchange on Δ47 of CO 2
Scientific Reports, 2021 The clumped isotope composition (Δ47, the anomaly of the mass 47 isotopologue relative to the abundance expected from a random isotope distribution) of CO2 has been suggested as an additional tracer for gross CO2 fluxes.

Leaf Age Affects Gas Exchange in Okra [PDF]
HortScience, 1995 Two studies were conducted to assess the effects of leaf aging on gas exchange in okra [Abelmoschus esculentus (L.) Moench] leaves. Gas exchange was measured at 6- to 10-day intervals starting 15 days after leaf emergence (DFE) and continuing until senescence at 50 DFE.

Estimating leaf day respiration from conventional gas exchange measurements
New Phytologist, 2023 SummaryLeaf day respiration (Rd) strongly influences carbon‐use efficiencies of whole plants and the global terrestrial biosphere. It has long been thought that Rd is slower than respiration in the dark at a given temperature, but measuring Rd by gas exchange remains a challenge because leaves in the light are also photosynthesizing. The Kok method and

Reduction of molecular gas diffusion through gaskets in leaf gas exchange cuvettes by leaf‐mediated pores [PDF]
Plant, Cell & Environment, 2013 AbstractThere is an ongoing debate on how to correct leaf gas exchange measurements for the unavoidable diffusion leakage that occurs when measurements are done in non‐ambient CO2 concentrations. In this study, we present a theory on how the CO2 diffusion gradient over the gasket is affected by leaf‐mediated pores (LMP) and how LMP reduce diffusive ...

Optimal allocation of leaf epidermal area for gas exchange [PDF]
New Phytologist, 2016 Summary A long‐standing research focus in phytology has been to understand how plants allocate leaf epidermal space to stomata in order to achieve an economic balance between the plant's carbon needs and water use. Here, we present a quantitative theoretical framework to predict allometric relationships between morphological stomatal traits in ...
