![]() ![]() Given the environmental conditions of high temperature and low relative humidity (RH) that occur during a heatwave, if soil water is limited, HS is associated with water stress (WS), due to the increased evaporative demand. A three-step band selection process allowed the identification of the spectral traits’ responsive to HS and combined stress, i.e., 1336–1340 nm, 1967–1971 nm, and 600–604 nm. However, their physiological recovery was not achieved within this time, as shown by the Simple Ratio Index (SRI), Transformed Chlorophyll Absorption Ratio Index (TCARI), and TCARI/Optimized Soil-Adjusted Vegetation Index (TCARI/OSAVI). The vines undergoing combined stress (SDI) showed greenness amelioration 10 days after stress, as revealed by the greenness vegetation indices (VIs), i.e., Green Index (GI), Normalized Difference Greenness Vegetation Index (NDGI), and Visible Atmospherically Resistant Index (VARI). Consistent with the physiological analysis, the proximal spectral responses of leaves identified SPRI and SI+ as putative cooling strategies to minimize vine HS. We also identified the spectral response of grapevine to HS and combined HS and WS (resulting from SDI). All the physiological indicators measured were significantly lower after the end of HS in the SDI treatment. Compared to the other treatments, in the early stages after the occurrence of HS, the vine water status of SPRI and SI+ improved, with high stomatal conductance ( g s) (SPRI) and stem water potential ( Ψ stem SPRI and SI+). The treatments were: standard drip irrigation (SI), extra drip irrigation (SI+), extra sprinklers irrigation (SPRI), and sustained deficit irrigation (SDI 50% of SI). Sauvignon blanc to individual (HS) and combined (HS + WS) stress under four different cooling and irrigation strategies. In this study, we evaluated the physiological and spectral responses of Vitis vinifera L. prompts you to turn on Bluetooth, tap OK to confirm.Heat stress (HS) and water stress (WS) pose severe threats to viticulture, and effective management solutions to counter their effects on grapevine performance must be examined.
