Use of infrared thermography for monitoring stomatal closure in the field: application to grapevine
Hamlyn G. Jones,Manfred Stoll,Tiago P. Santos,Claudia de Sousa,Maria Manuela Chaves,Olga M. Grant +5 more
TL;DR: This paper reviews and discusses strategies for the use of thermal imaging for studies of stomatal conductance in the field and compares techniques for image collection and analysis and evidence is presented that the temperature of reference surfaces exposed within the canopy can be affected by the canopy water status.
Journal ArticleDOI
Thermography to explore plant–environment interactions
TL;DR: This review presents and discusses the advantages of thermal imaging applications to plant science, agriculture, and ecology, as well as its limitations and possible approaches to minimize them, by highlighting examples from previous and ongoing research.
Journal ArticleDOI
Exploring thermal imaging variables for the detection of stress responses in grapevine under different irrigation regimes
TL;DR: It is suggested that the average temperatures of areas of canopies containing several leaves may be more useful for distinguishing between irrigation treatments than the temperatures of individual leaves.
Journal ArticleDOI
Estimating stomatal conductance with thermal imagery
TL;DR: The results suggest that estimates of the absolute magnitude of gs are somewhat subjective, depending on the skill of the experimenter at selecting evenly exposed leaves, and relative treatment differences in conductance are sensitively detected by different experimenters.
Journal ArticleDOI
Optimizing thermal imaging as a technique for detecting stomatal closure induced by drought stress under greenhouse conditions
TL;DR: In this paper, the robustness and sensitivity of thermal imaging for detecting changes in stomatal conductance and leaf water status in a range of plant species was analyzed, showing that thermal imaging successfully distinguished between irrigated and non-irrigated plants of a variety of species under greenhouse or controlled chamber conditions.
