Fig. 3From: Whole plant chamber to examine sensitivity of cereal gas exchange to changes in evaporative demandWhole plant transpiration (TrIRGA), photosynthesis (An) and intrinsic water use efficiency (iWUE) in different wheat cultivars at a single VPD (2.5 kPa ± 6%). Bars are mean ± SE of 5–6 biological replicates, with different letters indicating significant (P < 0.05) differences according to a Tukey testBack to article page
