Abstract

Water status in relation to standing biomass and leaf area indices (LAI) of the subtropical foredune species Arctotheca populifolia, Ipomoea pes-caprae and Scaevola plumieri were studied in the Eastern Cape, South Africa. The plants showed little evidence of water stress, never developing leaf water potentials more negative than −1.55 MPa, a value which is typical of mesophytes rather than xerophytes. The plants showed no seasonal changes in osmotic potential, an indication that they did not need to osmoregulate, nor were there significant alterations in tissue elasticity. Turgor potential for the most part remained positive throughout the day or recovered positive values at night, a condition suitable for the maintenance of growth that may be essential to cope with sand accretion. All three species show relatively high transpiration rates and only I. pes-caprae showed any evidence of strong limitations of transpiration rate through reductions in midday stomatal conductance. All three species had relatively high instantaneous water use efficiencies as a result of high assimilation rates rather than low transpiration rates. Simple water budgets, accounting for losses by transpiration and inputs from rainfall, suggest that the water stored in the dune sands is sufficient to meet the requirements of the plants, although water budgets calculated for I. pes-caprae suggest that this species may on occasion be water limited. The results suggest that it is the low biomass and LAI that lead to these favourable water relations.
