Daytime trend in environmental data, thermal infrared indices and leaf water potential of B104 plants. For the environmental data and indices, one day during the acute drought period was selected that corresponded with about 5 days after the onset of drought. For leaf water potential (ψ), all measurements collected during the experiment were used because of the limited number of B104 measurements per day. Average and individual environmental measurements (A–C) are shown with black lines and black dots, respectively. The average index and ψ values of the well-watered (WW) and water-deficit (WD) treatment are represented by a blue line and a red dashed line, respectively (D–G). The individual plants are visualized with blue dots (WW) and red circles (WD). Daytime patterns of meteorological data: (A) PAR in the growth zone (PARgz), (B) VPD inside the cabin (VPDin), and (C) air temperature inside the cabin (Ta_in). Morning patterns of TIR: (D) CSIin index, (E) TRIin index, and (F) CTDin index. (G) Daytime trend in leaf ψ
