Ecological implications of stomatal density and stomatal index in the adult stage of Mimosa L. (Leguminosae, Caesalpinioideae)

Protoplasma, 2023
Differences in stomatal density (SD) and stomatal index (SI) are associated with the conditions of the environment in which they are distributed. Mimosa species are important elements in different plant communities, yet knowledge of the ecological implications of its stomatal characteristics is scarce.

Stomatal density and stomatal index as indicators of paleoatmospheric CO2 concentration

Review of Palaeobotany and Palynology, 2001
A growing number of studies use the plant species-specific inverse relationship between atmospheric CO(2) concentration and stomatal density (SD) or stomatal index (SI) as a proxy for paleo-CO(2) levels. A total of 285 previously published SD and 145 SI responses to variable CO(2) concentrations from a pool of 176 C(3) plant species are analyzed here ...

Effect of Culture Conditions on Stomatal Density and Stomatal Index in Four Cactus Species

Haseltonia, 2015
Abstract: We evaluated type of stomata, as well as differences in stomatal frequency in three areas of the plant (apical, middle and basal) under two culture conditions (in vitro and ex vitro), in four cactus species (Opuntia ficus-indica, Hylocereus undatus, Escontria chiotilla and Mammillaria petterssonii).

Density gradient centrifugation studies of vesicular stomatitis virus

Archiv f�r die gesamte Virusforschung, 1965
Equilibrium sedimentation in caesium chloride has been used to separate and study the biologically active components of vesicular stomatitis virus (Indiana) grown in baby hamster kidney cells and chick embryos. Infective egg fluid was shown to contain two infective components of densities 1.191 g/ml. and 1.217 g/ml.

Stomatal Density Responses to Global Environmental Change

1996
The CO2concentration of the Earth’s atmosphere is steadily increasing as a result of anthropogenic activities such as the combustion of fossil fuels and tropical deforestation which release stored carbon from terrestrial sinks. This accumulation of CO2in the atmosphere is the one fact in the global climate change debate upon which all scientists agree (

Sampling Stomatal Density in Alfalfa1

Crop Science, 1981
Sample size requirements for stomatal density studies in alfalfa (Medicago sativa L.) are not documented. This study was conducted to refine sampling techniques and to determine whether the sampling required to estimate stomatal density is too extensive to use this trait as a possible rapid screening criterion for drought resistance in alfalfa.Stomatal

Cell expansion coordinates leaf vein and stomatal density

2023
The efficiency with which water is delivered through leaf tissue to sites of evaporation (the leaf hydraulic conductance) is an important determinant of photosynthetic capacity. This is because inadequate water supply forces stomata to close due to plant desiccation. The resulting reduction in stomatal conductance restricts carbon dioxide (CO2) uptake.

Bounds on stomatal size can explain scaling with stomatal density in forest plants

New Phytologist
Summary A prevailing hypothesis posits that achieving higher maximum rates of leaf carbon gain and water loss is constrained by geometry and/or selection to limit the allocation of epidermal area to stomata ( f

Modelling of stomatal density response to atmospheric CO2.

Journal of theoretical biology, 2008
Stomatal density tends to vary inversely with changes in atmospheric CO(2) concentration (C(a)). This phenomenon is of significance due to: (i) the current anthropogenic rise in C(a) and its impact on vegetation, and (ii) the potential applicability for reconstructing palaeoatmospheric C(a) by using fossil plant remains.
