Turgor pressures in the cells of some halophytes measured using a cell pressure probe

Turgor pressure (MPa)	Species	Comment	Reference
0·20	Suaeda maritima	The maximum turgor pressure in cells of the youngest leaves of plants growing in 400 mm NaCl. The minimum turgor in old leaves was 0·050 MPa.	Clipson et al. (1985)
0·16	Mesembryanthemum crystallinum	Maximum turgor pressure in root cortical cells (layer 3, 25 mm from the tip) of plants growing in 400 mm NaCl.	Rygol and Zimmermann (1990)
0·10	Aster tripolium	Rhizodermis of plants growing in 300 mm NaCl. Maximum turgor pressure in root cortical cells (layer 7, 20 mm from the tip) was 0·6 MPa.	Zimmermann et al. (1992)
0·33	Sarcobatus vermiculatus	Pre-dawn in mature leaves of plants growing in 300 mm NaCl.	James et al. (2006)
0·22	Sarcobatus vermiculatus	Mid-day in mature leaves of plants growing in 300 mm NaCl.	James et al. (2006)
