Thermal infrared imaging of crop canopies for the remote diagnosis and quantification of plant responses to water stress in the field por Jones, Hamlyn G., Serraj, Rachid, Loveys, Brian R., Xiong, Lizhong, Wheaton, Ashley, Price, Adam H.

“…This paper outlines the potential applications of IR sensing in drought phenotyping, with particular emphasis on a description of the problems with extrapolation of the technique from the study of single leaves in controlled environments to the study of plant canopies is field plots, with examples taken from studies on grapevine (Vitis vinifera L.) and rice (Oryza sativa L.). Particular problems include the sensitivity of leaf temperature (and potentially the temperature of reference surfaces) to both temporal and spatial variation in absorbed radiation, with leaf temperature varying by as much as 15°C between full sun and deep shade. …”

C4 rice: a challenge for plant phenomics por Furbank, Robert T., von Caemmerer, Susanne, Sheehy, John, Edwards, Gerry

“…There is now strong evidence that yield potential in rice (Oryza sativa L.) is becoming limited by ‘source’ capacity, i.e. photosynthetic capacity or efficiency, and hence the ability to fill the large number of grain ‘sinks’ produced in modern varieties. …”
