Statistical comparisons of the guard cell-apoplast Suc contents, the guard cell-symplast Suc contents, and stomatal aperture sizes at a constant 60% RH versus cognate values obtained when the RH was shifted to 90% 8 h prior to the onset of illumination

Time	P Values, Parameter at 60% RH versus 90% RH
	Guard cell Suc content		Stomatal aperture size
	Apoplast	Symplast

0900	0.93	0.02	0.51
1100	0.01	0.02	0.02
1300	0.02	0.02	<0.01

The compared values are derived from Figure 1, which provides other details.
