“…anisohydric and isohydric plants (Stocker, 1956). In both types, the predawn Ψ decreases with the drought, but while anisohydric plants show large differences in midday Ψ amongst watering treatments, the isohydric plants do not show appreciable differences in midday Ψ (Tardieu and Simmoneau, 1998).…”

Diurnal courses of gas exchange, chlorophyll fluorescence, shoot water potential (Ψ ) and leaf relative water content (RWC leaf ) were recorded in Chamaecytisus proliferus (L. fil.) Link ssp. proliferus var. palmensis (Christ) (tagasaste) growing in natural conditions in the North-West slope of Tenerife, Canary Islands. During the studied period (April-July 2000), the soil relative water content (RWC soil ) progressively decreased, while the air vapour pressure deficit increased. As a consequence a decrease in Ψ and RWC leaf took place as well as a decrease in stomatal conductance (g s ) and CO 2 assimilation rate (A). These characteristics, typical of an anisohydric plant, allowed this species to endure a mild drought.Photochemical efficiency of PSII (φ PSII ) followed the inverse pattern to that observed for the photosynthetic photon flux density (PPFD), decreasing at midday and recovering during the late afternoon. This recovering at the end of each day, and the constant values of the maximum quantum yield of PSII photochemistry (F v /F m ) during the studied period, indicate that there was no permanent damage to the photosynthetic apparatus due to mild water stress.

“…Transpiration was measured in detached leaves with a torsion balance according to Stocker (1956) in the three species with intervals of 1 hr during days of different weather in the dry and rainy seasons of 1969. Evaporation with Piche evaporimeter was measured simultaneously.…”

“…In dicots, this problem has been clearly demonstrated by Franco and Magalhaes (1965), but in grasses, stomatal control of transpiration seems to be less effective, and they do not restrict water losses under water stress, but transpire further until leaves dry out (Walter, 1964;Stocker, 1956).

“…One major task of ecophysiological research is to elucidate the regulation of water relations for the efficient utilisation of the limited resource. During dry periods plants generally reduce transpiration by midday or even permanent stomatal closure Lo¨sch et al, 1982;Schulze et al, 1980;Stocker, 1956;Tenhunen et al, 1981). Under such conditions it is assumed that plant life largely depends on the efficacy of the cuticular transpiration barrier in order to reduce uncontrolled water loss to the atmosphere and to maintain an adequate plant water status for survival (Burghardt and Riederer, 2006;Riederer and Schreiber, 2001;Scho¨nherr, 1982).…”
