Measurement of Gas Exchange on Excised Grapevine Leaves Does Not Differ from In Situ Leaves, and Potentially Shortens Sampling Time

open access: yesApplied 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 ...

An Improved System to Measure Leaf Gas Exchange on Adaxial and Abaxial Surfaces

open access: yesBio-Protocol, 2023
Measurement of leaf carbon gain and water loss (gas exchange) in planta is a standard procedure in plant science research for attempting to understand physiological traits related to water use and photosynthesis. Leaves carry out gas exchange through the

Water Costs of Gas Exchange by a Speckled Cockroach and a Darkling Beetle

open access: yesInsects, 2020
Respiratory water loss during metabolic gas exchange is an unavoidable cost of living for terrestrial insects. It has been suggested to depend on several factors, such as the mode of gas exchange (convective vs.

Monitoring Gas Exchange [PDF]

open access: yesRespiratory Care, 2020
Critical illness can threaten the adequacy of O2 delivery or CO2 excretion. Monitoring seeks to identify the adequacy of oxygenation and ventilation and to detect deterioration early. Advances in oximetry, capnography, and transcutaneous CO2 monitoring offer new opportunities for more accurate estimation of gas exchange, noninvasive monitoring of ...

Quantitative effects of environmental variation on stomatal anatomy and gas exchange in a grass model

open access: yesQuantitative Plant Biology, 2022
Stomata are cellular pores on the leaf epidermis that allow plants to regulate carbon assimilation and water loss. Stomata integrate environmental signals to regulate pore apertures and adapt gas exchange to fluctuating conditions.
