The data in this table are expressed as the means ± sd (shown in parentheses) from 10 measurements of three independent experiments, according to Student's t distribution analysis with 95% confidence intervals.
a
Ψp was not experimentally determined; it was calculated from the difference between the Ψw and the Ψs values.
b
C, Control.
c
WD, Water deficient.
