Whole plant transpiration (TrIRGA), net photosynthesis (An) and intrinsic water use efficiency (iWUE) in the wheat cultivars Drysdale (a–c) and Krichauff (d–f), and the wild-type barley cultivar cv. Steptoe (g–i) and its ABA-deficient mutant Az34 (j–l). Each point is from an individual plant, for 5–6 different plants per genotype. Dark blue dots represent plants measured in March–April 2017 while light blue dots represent plants measured in August–September 2017. Average values for each data set are indicated, with letters indicating significant (P < 0.05) differences between means when comparing either wheat or barley genotypes. Regression and break point analysis are available in Additional file 1: Tables S1–S3, with summary information included in each graph; ns, no significant difference
