(A) Aboveground dry mass and (B) applied water use efficiency of wheat plants subjected to well-watering (ctr), continuous (cd) and pulsed (pd) drought, harvested at two time points (T1 = 77 d and T2 = 93 d after sowing). The applied water use efficiency was calculated for each pot as the ratio of aboveground plant dry mass to the cumulative amount of water received until harvest. At T2, values are given for vegetative (leaves and stems) and generative plant parts (ears). The boxes represent the interquartile ranges, whiskers extend to the 10% and 90% percentiles, respectively; solid lines show the medians, dashed lines the means. Outliers are shown as circles; when there was a significant effect of irrigation treatment (Table 2), manual contrasts between selected groups were calculated and p values are given; ***p < 0.001; **p < 0.01; *p < 0.05; (n.s.) marginally significant (p < 0.1); n.s. not significant; n = 10.
