Leaf area, specific leaf area (SLA) and tiller number measured when the early season drought treatment was ended at 30 DAS, and 50% anthesis (Z61) in in three wheat cultivars with different root systems, grown under well-watered conditions (WW) and exposed to early season drought (ESD). ESD was induced by simulating a 25 mm rainfall after sowing in dry soil and no watering for 30 days.
