The only plants that maintained positive turgor values after 8 d of drought
were those grown at 380mol mol−1 CO2, particularly in the case
of those sprayed with AT, for which the OA, relative to their respective
watered controls, was also greatest (−0.308, compared with
−0.251MPa for non-sprayed plants at 380molmol−1 CO2,−0.126
for AT-sprayed plants and −0.038MPa for non-sprayed plants at
2000molmol−1 CO2).
