Science of the Total Environment
The stomatal index (SI, %) and its response to climate factors (temperature and precipitation) can help our understanding of terrestrial carbon and water cycling and plant adaptation in the ecosystem, however, consensus has not yet been reached in this regard.

Stomatal Structure in Symphyotrichum Nees Species as an Additional Index of Invasiveness
Russian Journal of Biological Invasions, 2021The study was aimed on a comparison of morphometric traits of the stomatal apparatus in cultivated Symphyotrichum Nees species to evaluate the adaptive capacity of these alien taxa. The study included eleven Symphyotrichum species from the collection of the Botanical Garden of Padua (Italy): S. novi-belgii, S. novae-angliae, S. ciliolatum, S. laeve, S.

Effects of Various Environmental Factors on Stomatal Density, Area, and Potential Conductance Index
Journal of Emerging Investigators, 2021Stomata, microscopic pores on a leaf flanked with flexible guard cells that open and close the stomatal opening, account for 95% of terrestrial movement of water vapor and carbon essential to the survival of plants. The climate crisis is challenging plants with elevated CO2, drought, varying soil salinity, varying soil acidity, and increasing ...

Assessing the potential for the stomatal characters of extant and fossil Ginkgo leaves to signal atmospheric CO2 change [PDF]
American Journal of Botany, 2001 The stomatal density and index of fossil Ginkgo leaves (Early Jurassic to Early Cretaceous) have been investigated to test whether these plant fossils provide evidence for CO2-rich atmosphere in the Mesozoic.

Stomatal Distribution as an Index for Predicting the Growth Potential of Apple Stocks
Journal of Horticultural Science, 1976SummaryIn the present study 27 apple rootstocks have been classified into five vigour groups, according to their stomatal distribution, which varied from 11·55 to 5·88 per unit area. Amongst the different stocks studied M. 25 had the maximum stomatal frequency, and M. 9 had the least. An indigenous apple clone M. boccata var.

Oecologia, 2011
The inverse relationship between the number of stomata on a leaf surface and the atmospheric carbon dioxide concentration ([CO(2)]) in which the leaf developed allows plants to optimise water-use efficiency (WUE), but it also permits the use of fossil plants as proxies of palaeoatmospheric [CO(2)].

Review of Palaeobotany and Palynology, 2012
Abstract The inverse relationship between the number of stomata on the surface of a leaf and the atmospheric concentration of carbon dioxide ([CO2]) in which it developed permits the use of fossil plants as indicators of palaeo-atmospheric [CO2] level (palaeo-[CO2]).

Journal of Oral Pathology & Medicine, 2009
Background: Although number, frequency and healing time of oral ulcers and pain are generally used for clinical practice and studies in Behcet’s disease (BD) and recurrent aphthous stomatitis (RAS), no standardized activity index is currently present to monitor clinical manifestations associated with oral ulcers. The aim of this study was to develop a

Cycads show no stomatal-density and index response to elevated carbon dioxide and subambient oxygen
Australian Journal of Botany, 2011The stomatal density (SD) and index (SI) of fossil plants are widely used in reconstructing palaeo-atmospheric CO2 concentration (palaeo-[CO2]). These stomatal reconstructions depend on the inverse relationship between atmospheric CO2 concentration ([CO2]) and SD and/or SI.
