Rp. Beckett, THE WATER RELATIONS OF THE MARITIME LICHEN ROCCELLA-HYPOMECHA (ACH) BORG STUDIED USING THERMOCOUPLE PSYCHROMETRY, South African journal of botany, 62(2), 1996, pp. 122-125
The water relations of the maritime lichen Roccella hypomecha were inv
estigated using thermocouple psychrometry. Results showed that, while
containing high concentrations of Na+, the osmotic potential and other
aspects of the water relations of R. hypomecha resembled those of lic
hens growing in xeric non-saline habitats. The significance of these r
esults for the water relations of maritime lichens is discussed.
