Figure 2. Gas exchange measurements and intrinsic water use efficiency in the conventional soybean cultivar BRS 184 and its isoline, the transgene 2Ha11 AtNCED3, under water deficit induced in greenhouse conditions. Means ± standard error of nine replicates. The means followed by the same letters do not differ by the Duncan test (p≤0.05). The uppercase letters compare GM line and conventional cultivar (2Ha11/BRS184) and the lowercase letters compare water conditions (control/drought).
