In addition, gsfell to values near zero at 7%PEG in these genotypes. By contrast, stomata closed to values near0.1 mol m−2s−1in 12/cultivar and 14/cultivar plants, irrespective ofthe stress level (Fig. 4C), and did not change at T2 (Fig. 4D). Stomatalconductance was also strongly reduced in the ungrafted, 5/cultivar,and 8/cultivar plants at T2.
