Abstract:

Plant drought response mechanism is very complicated, stomatal movement is one of the mechanisms of plant adaptation to drought stress. General stomatal behavior change will directly reflect on some physiological indexes such as stomatal conductance, transpiration intensity change, thus resulting in the increase of leaf temperature. Once encounter stresses such as drought, leaf temperature changes will be used to monitor and diagnosis of plant stress condition. Infrared thermography technology can convert thermal radiation of a target object into color pictures we can see, which have characteristic with high resolution, non-contact, high-throughput. In this study, the mechanism of plant response to drought, as well as the infrared technology application in plant drought resistance research was reviewed to clarify the infrared thermography to study the mechanisms of plant response to drought, proposed the possibility of infrared thermography technology applying in the plant breeding for drought-resistance.
