A Deep Learning-Based Method for Automatic Assessment of Stomatal Index in Wheat Microscopic Images of Leaf Epidermis [PDF]
Frontiers in Plant Science, 2021 The stomatal index of the leaf is the ratio of the number of stomata to the total number of stomata and epidermal cells. Comparing with the stomatal density, the stomatal index is relatively constant in environmental conditions and the age of the leaf ...

Differences in the response sensitivity of stomatal index to atmospheric CO2 among four genera of Cupressaceae conifers. [PDF]
Annals of Botany, 2010 The inverse relationship between stomatal density (SD: number of stomata per mm(2) leaf area) and atmospheric concentration of CO2 ([CO2]) permits the use of plants as proxies of palaeo-atmospheric CO2. Many stomatal reconstructions of palaeo-[CO2] are based upon multiple fossil species.

An Intrinsic Geometric Constraint on Morphological Stomatal Traits
Frontiers in Plant Science, 2021 A strong negative non-linear relationship exists between stomatal density (SD) and size (SS) or length (SL), which is of high importance in gas exchange and plant evolution. However, the cause of this relationship has not been clarified.

Systemic immune inflammation index in patients with recurrent aphthous stomatitis
Brazilian Journal of Otorhinolaryngology, 2022 Recurrent Aphthous Stomatitis (RAS) a chronic idiopathic oral mucosal disease. But yet the etiology and pathogenesis of RAS are not exactly known, it is thought that inflammation play an important role in the pathogenesis. The aim of this study is to demonstrate the role of systemic inflammation among the possible etiological factors of RAS and to find

Biological Significance of Changes in Stomatal Density and Stomatal Index of Aloe Species
Innovations in STEAM: Research & Education, 2023 Aloe is a genus containing over 500 species of flowering succulent plants with enormous medicinal potential. Stomatal density and index vary greatly in the different species of this genus. Aloe species were collected from the new botanical garden, University of Agriculture, Faisalabad.
