Estimating stomatal conductance of citrus under water stress based on multispectral imagery and machine learning methods

Abstract: IntroductionCanopy stomatal conductance (Sc) indicates the strength of photosynthesis and transpiration of plants. In addition, Sc is a physiological indicator that is widely employed to detect crop water stress. Unfortunately, existing methods for measuring canopy Sc are time-consuming, laborious, and poorly representative.MethodsTo solve these problems, in this study, we combined multispectral vegetation index (VI) and texture features to predict the Sc values and used citrus trees in the fruit growth period… Show more

“…This DOM was input into the image processing software ENVI5.3, and the Di value of the corresponding band was extracted by dividing the region of interest (ROI) [26]. Then, the spectral reflectance Ri of each band was calculated according to Formula (1) [27]. To mitigate the impact of the solar irradiation angle on the multi-spectral images, this study conducted the collection of multi-spectral images at noon during sunny weather.…”
