Phenotyping of rice (Oryza sativa L. cv. Donggin) in salt stress environment using infrared imaging was conducted. Results were correlated with the most frequently used physiological parameters such as stomatal conductance, relative water content and photosynthetic parameters. It was observed that stomatal conductance (R² = -0.618) and relative water content (R² = -0.852) were significantly negatively correlated with average plant temperature (thermal images), while dark-adapted quantum yield (Fᵥ/Fₘ, R² = -0.325) and performance index (R² = -0.315) were not consistent with plant temperature. Advantages of infrared thermography and utilization of this technology for the selection of stress tolerance physiotypes are discussed in detail.
