Interspecific variation in nighttime transpiration and stomatal conductance in a mixed New England deciduous forest.
Transpiration is generally assumed to be insignificant at night when stomata close in response to the lack of photosynthetically active radiation. However, there is increasing evidence that the stomata of some species remain open at night, which would allow for nighttime transpiration if there were a sufficient environmental driving force. We examined nighttime water use in co-occurring species...
متن کاملUpdate on Nighttime Stomatal Conductance in Plants Nighttime Stomatal Conductance and Transpiration in C3 and C4 Plants 1[W]
Incomplete stomatal closure during the night is observed in a diverse range of C3 and C4 species (Fig. 1; Supplemental Table S1) and can lead to substantial nighttime transpirational water loss. Although water loss is an inevitable consequence of stomatal opening for photosynthetic carbon gain, nighttime stomatal opening is unexpected because carbon gain is not occurring and the need to cool le...

متن کاملTranspiration and stomatal conductance across a steep climate gradient in the southern Rocky Mountains
Transpiration (E) is regulated over short time periods by stomatal conductance (Gs) and over multi-year periods by treeand stand-structural factors such as leaf area, height and density, with upper limits ultimately set by climate. We tested the hypothesis that tree structure, stand structure and Gs together regulate E per ground area (Eg) within climatic limits using three sites located across...
متن کاملA coupled model of photosynthesis, stomatal conductance and transpiration for a rose leaf (Rosa hybrida L.).
The following three models were combined to predict simultaneously photosynthesis, stomatal conductance, transpiration and leaf temperature of a rose leaf: the biochemical model of photosynthesis of Farquhar, von Caemmerer and Berry (1980, Planta 149: 78-90), the stomatal conductance model of Ball, Woodrow and Berry (In: Biggens J, ed. Progress in photosynthesis research. The Netherlands: Marti...
