With sub-nanometric images, the photosynthesis in different phases of water stress in almond trees and the physiological changes caused by vascular pathogens in olive trees are being studied. The Institute of Sustainable Agriculture of the Spanish National Research Council (IAS-CSIC) has coordinated two studies that use sub-nanometric technology - hyperspectral images obtained with a resolution between 100 and 300 times higher than that of standard sensors - and thermography to detect physiological variations that allow for a better understanding of the effects of irrigation on photosynthesis, as well as the early detection of pests and diseases. Specifically, the study published in Remote Sensing of Environment, the most prestigious journal in the field of remote sensing, represents an advance that reveals how remote sensing with sub-nanometric spectral resolution is able to capture the dynamics of photosynthesis and transpiration during different phases of water stress, as well ...
