Pore size regulates operating stomatal conductance, while stomatal densities drive the partitioning of conductance between leaf sides

Pore 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...

Establishing 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...

A 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...
