Smaller, faster stomata: scaling of stomatal size, rate of response, and stomatal conductance
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 (op)) correlates with minimum stomatal c...
متن کاملStomatal development in new leaves is related to the stomatal conductance of mature leaves in poplar (Populus trichocarpaxP. deltoides).
In general, stomatal density (SD) decreases when plants are grown at high CO2 concentrations. Recent studies suggest that signals produced from mature leaves regulate the SD of expanding leaves. To determine the underlying driver of these signals in poplar (Populus trichocarpaxP. deltoides) saplings, a cuvette system was used whereby the environment around mature (lower) leaves could be control...
متن کاملPore size regulates operating stomatal conductance, while stomatal densities drive the partitioning of conductance between leaf sides.
BACKGROUND AND AIMS Leaf gas exchange is influenced by stomatal size, density, distribution between the leaf adaxial and abaxial sides, as well as by pore dimensions. This study aims to quantify which of these traits mainly underlie genetic differences in operating stomatal conductance (gs) and addresses possible links between anatomical traits and regulation of pore width. METHODS Stomatal r...
متن کاملEstablishing the relationship between stomatal conductance and microclimate through a model of stomatal conductance
through a model of stomatal conductance Jinzhi Wang Introduction I came to CGREC on May 7, 2008 to work under the direction of Dr. Xuejun Dong, eco-physiologist at the Center. His work involves the relationship between environmental factors (precipitation, temperature, and radiation) and soil respiration and plant physiology (leaf photosynthetic rates and leaf area index) of dominant species. O...
متن کاملA modified optimal stomatal conductance model under water-stressed condition
Accurate estimation of leaf stomatal conductance (gs) is important in predicting carbon andwater cycles of terrestrial ecosystem. To estimate gs on field-grown soybean and maize underwater-stressed condition accurately, a modified optimal stomatal conductance (OSCM) modelwas established based on the relationship between marginal water cost of carbon gain and soilwater content by introducing a w...
