Stomatal sensitivity to photosynthetic and environmental signals in glycine max grown at elevated atmospheric concentrations of CO2 and O3
… Variation in maximum carboxylation capacity (Vcmax) as a result of plant growth in elevated [CO2] or elevated [O3] will change the A that a given ci, permitted by a given gs, will support. Such a Vcmax-induced change in the sensitivity of gs to A may contribute to a change in m. Soybean was …

Characterizing natural genetic variation in photosynthetic efficiency across 44 accessions and five subpopulations of oryza sativa
… efficiency, maximum rate of carboxylation (Vcmax) maximum electron transport rate (Jmax), and triose-phosphate use (TPU) limitations – among 25 other traits. For example, subpopulation tropical japonica had the highest values for both Vcmax and Jmax, and demonstrated 11.9% and 19% higher …

Temperature dependence of plant photosynthesis and respiration using the Macromolecular Rate Theory (MMRT)
… light (DL), the maximal carboxylation capacity (Vcmax), the maximal electron transport capacity (Jmax), and the components of dark respiration (Rdark). The central objective was to identify temperature dependence models for each trait that were both parsimonious and physiologically interpretable. …

Water use of forests along elevation gradients in the Berchtesgaden National Park
… patchiness as well as carboxylation capacity (Vcmax) may have had an influence on stand water use. The modelled transpiration with changes in Vcmax was similar to estimated transpiration rates obtained by changing the “portion of leaves that are active” (stomatal patchiness). The developed …

Diagnostische Relevanz der Impuls-Oszillometrie im Vergleich zur Bodyplethysmographie im Kindesalter
… Variationskoeffizienten (CV) von z. B. 2,0% für VCmax und 3,7% für FEV1 an der Spitze. Die Parameter der Fluss - Volumen - Messung erreichten CV um 10%. Für die BP errechneten sich 5,0% für das ITGV und 11,6% bzw. 13,8% für den absoluten bzw. spezifischen effektiven Atemwegswiderstand. Sämtliche …

Water balance and productivity of a Mediterranean oak woodland : Quantifying understory vegetation impacts by development of a stable oxygen isotope partitioning approach
… and decreased maximum carboxylation rate (Vcmax) of cork-oaks. Moreover, the drought in 2012 led to strong alterations in tree phenology: annual tree diameter increment and fruit production were severely reduced. These findings suggest that the herbaceous understory, although vulnerable to …

Impacts of heat waves on food quantity and quality of soy bean/corn in the Midwest at ambient and elevated [CO2]
… i.e. the maximum rate of rubisco carboxylation (Vcmax ) or the maximum rate of electron transport (Jmax). Additionally, because soybeans flower and set pods for 25-35 days it was hypothesized that any direct reproductive damage would be negligible due to the long flowering time and high number of …

Productivity, physiology, community dynamics, and ecological impacts of a grassland agro-ecosystem: integrating field studies and ecosystem modeling
Grasslands are among the largest ecosystems in the world and provide numerous ecosystem services. These services include the ecosystem benefits important in an agricultural context such as biomass production and benefits from an ecological perspective such as mitigation of greenhouse gas emissions. …
