Smaller, faster stomata: scaling of stomatal size, rate of response, and stomatal conductance [PDF]

Journal of Experimental Botany, 2013
Maximum and minimum stomatal conductance, as well as stomatal size and rate of response, are known to vary widely across plant species, but the functional relationship between these static and dynamic stomatal properties is unknown. The objective of this study was to test three hypotheses: (i) operating stomatal conductance under standard conditions (g

Genome size is a strong predictor of cell size and stomatal density in angiosperms [PDF]

New Phytologist, 2008
Across eukaryotes phenotypic correlations with genome size are thought to scale from genome size effects on cell size. However, for plants the genome/cell size link has only been thoroughly documented within ploidy series and small subsets of herbaceous species. Here, the first large-scale comparative analysis is made of the relationship between genome

Stomatal Size, Speed, and Responsiveness Impact on Photosynthesis and Water Use Efficiency   [PDF]

Plant Physiology, 2014
AbstractThe control of gaseous exchange between the leaf and bulk atmosphere by stomata governs CO2 uptake for photosynthesis and transpiration, determining plant productivity and water use efficiency. The balance between these two processes depends on stomatal responses to environmental and internal cues and the synchrony of stomatal behavior relative

Genetic manipulation of stomatal density influences stomatal size, plant growth and tolerance to restricted water supply across a growth carbon dioxide gradient [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2012
To investigate the impact of manipulating stomatal density, a collection of Arabidopsis epidermal patterning factor (EPF) mutants with an approximately 16-fold range of stomatal densities (approx.

Cannabis sativa genotypes with larger leaf areas have higher potential to adjust stomatal size and density in response to water deficit: The effect on stomatal conductance and physiological stomatal behaviour

Plant Stress
Effective stomatal control is fundamental to successful plant responses to water deficit stress. Control of stomatal conductance (Gs) can be exerted through modification of stomatal morphology (size and density) in newly developing leaves, or ...

Stomatal Number and Size of Dicotyledon Plants

EPiC Series in Biological Sciences, 2021
The stomatal number and size influence transpiration, a process of water loss in the plant that cools its environmental temperature. Some dicotyledon plants function as shading plants, especially in the urban area. However stomatal number and size of some plants are not known. This study aimed to know the stomatal number and size in dicotyledon shading

Ecophysiological plasticity of Theobroma cacao L. clones in response to the structure and microclimate of agroforestry systems in Mexico

Botan‪ical Sciences, 2022
Background: Cocoa is a species commonly cultivated under agroforestry systems (AFs), when microclimate conditions are adequate, it achieves high growth rates and seed yield. Questions and Hypotheses: How do four cocoa varieties respond to open (OC) and

Scaling between stomatal size and density in forest plants [PDF]

, 2021
AbstractThe size and density of stomatal pores limit the maximum rate of leaf carbon gain and water loss (gmax) in land plants. The limits ofgmaxdue to anatomy, and its constraint by the negative correlation of stomatal size and density at broad phylogenetic scales, has been unclear and controversial. The prevailing hypothesis posits that adaptation to

Optimization of leaf morphology in relation to leaf water status: A theory. [PDF]

, 2020
The leaf economic traits such as leaf area, maximum carbon assimilation rate, and venation are all correlated and related to water availability. Furthermore, leaves are often broad and large in humid areas and narrower in arid/semiarid and hot and cold ...
