Overview of growth conditions and watering experiments. (a) Short‐dehydration experiment carried out on 12 ecotypes and the RIL population. Plants were grown for most of their lifespan under short‐day (65 days) and well‐watered conditions with a short‐dehydration period to assess plant water use and drought sensitivity (b) Continuous maintenance of moderate drought experiment carried out on 12 ecotypes and near‐isogenic lines (NILs). Plants were grown for most of their lifespan under long‐day and moderate drought conditions (40% rSWC; Bechtold et al., 2013, 2010). VWU: vegetative water use; PWU: lifetime plant water‐use; DP: dehydration plasticity. See Table 1 for glossary of terms
