Table 1 A detailed explanation of the experiments done with plants at Zadok’s stage 39–42. Spring experiments occurred between March and April, while summer experiments occurred between August and September

Experiment | Question | No of genotypes | No of reps | VPD | Approx. time per measurement | Period |
|---|---|---|---|---|---|---|
Exp. 1 | Is there genetic diversity in whole plant gas exchange at a single VPD? | 7 (Wheat) | 5–6 | 2.5 kPa | 15 min | Spring 2017 |
Exp. 2 | Does whole plant iWUE vary in response to VPD? | 4 (Wheat and Barley) | 2–3 | 0.75–4 kPa | 3–4 h | Spring 2017 |
Exp. 3 | Are results robust across experiments at different times of year? | 4 (Wheat and Barley) | 2–3 | 0.5–3.75 kPa | 3–4 h | Summer 2017 |
Exp. 4 | What is the mechanism behind Az34 response to ABA spraying? | 2 (Barley) | 4–5 | 1.5 kPa | 7 min; sampling | Spring 2018 |
