Variability of stomatal density and index in the Upper Permian conifer Quadrocladus Mädler—a taphonomical case study

Palaeogeography, Palaeoclimatology, Palaeoecology, 2005
Abstract Changes in atmospheric CO 2 concentrations over the geological past have attracted a considerable amount of scientific interest during the last decade. Many authors have demonstrated, that for some extant plants, stomatal densities and indices are negatively correlated with atmospheric CO 2 concentrations.

The effect of rootstock on the anatomy of the Phaseolus vulgaris L. scion: graft union, stomatal density, stomatal index, and leaf thickness

Agro Productividad
Objective: To evaluate the effect of the Phaseolus acutifolius A. Gray rootstock on the establishment of the Phaseolus vulgaris L. scion, analyzing the anatomy of the graft union, stomatal density, stomatal index, and leaf thickness. Design/Methodology/Approach: A completely randomized experimental design was used.

A composite index for determining the impact of oral ulcer activity in Behcet’s disease and recurrent aphthous stomatitis

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

Stomata Characteristics, stomatal density and stomatic index in redwood (Sequoia sempervirens) and its variation in different plantations in Chile

2017
Varios autores sugieren que los estomas de secuoya (Sequoia sempervirens) pueden presentar cambios morfológicos cuando esta especie crece en áreas con ausencia de criptoprecipitación. En este trabajo se estudiaron las características de los estomas, densidad e índice estomático en hojas de secuoya en función del nivel de precipitación, suelo ...

Climate factors determine large-scale spatial patterns of stomatal index in Chinese herbaceous and woody dicotyledonous plants

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.

Systemic immune inflammation index as a useful prognostic indicator in the prediction of chronic aphthous stomatitis

SUCHASNA STOMATOLOHIYA
Relevance. Chronic recurrent aphthous stomatitis (RAS) is one of the most common chronic inflammatory diseases of the oral cavity, which affects approximately 5 to 25% of the population. RAS is a multifactorial disorder, and studies have pointed to several potential causes associated with its occurrence.

Light Spectrum Effect on Stomatal Characteristics of Okra Leaves - Relationship Between NDVI and Leaf Area Index

Light quality plays a crucial role in the physiological responses of plants, particularly in stomatal behavior and canopy development. This study investigated the effects of different light spectra blue (B, 445 nm), red (R, 660 nm), and an alternating red-blue cycle every three days (R3B3) on okra (Abelmoschus esculentus), compared to natural light ...
