Determination of the gas exchange phenology
Web WebMar 24, 2024 · The water potential at stomatal closure is generally determined through stomatal sensitivity curves, which describe the loss of stomatal conductance as leaf water potential decreases (Brodribb & Holbrook, 2003; Creek et al., 2024 ). However, the necessary measurements for this approach are long and laborious, especially for tall …
