The aim of this study was to use hyperspectral remote sensing techniques to investigate the spectral responses of Vitis vinifera to increased CO2 concentrations in atmosphere air, where CO2 was injected into air of the OTC modified, which show 2 m of diameter and 1,2 m height. The specific aims were: (1) to assess the changes in Vitis vinifera plant chlorophyll content due to the leakage of CO2 into the plant-air environment and (2) to analyze an vegetation index derived from the first derivative reflectance values for use in detecting Vitis vinifera plant stress due to elevated concentrations of air CO2.
