From: Predawn leaf water potential of grapevines is not necessarily a good proxy for soil moisture
Predawn leaf water potential (Ψpd) of 30 grape cultivars plotted as a function soil water potential (Ψsoil) over two years with a linear regression line plotted in black, and grey-shaded bands showing the 95% confidence interval. The empty symbol (○) represents the 2021 data and the filled symbol (●) is 2022. The dashed lines are the minimal and maximal Ψsoil values from retention curves of 9 soil samples shown as the confidence interval in Fig. 1. The slopes and intercepts of the linear models are reported in Table 2
