Putting Pressure Chamber Values into Context Using the Calculated Non-Stressed Baseline

Nearly 40 years after its first documented use in grapevines, the pressure chamber (“pressure bomb”) remains the gold standard tool for determining vine water status. Whether one chooses to measure midday leaf water potential (ψleaf) or midday stem water potential (ψstem), the pressure bomb informs us how stressed our vines are and helps us decide whether to irrigate. A review …
