“…The present evidence that TE increases following rehydration is inconclusive (Fig. 6b) even though Larcher, De Moraes & Bauer (1981) observed increased TE in the potted olive trees after several cycles of water deficits. The significance of a consistent TE‐VPD relationship over a wide range of water status, suggest that it may be possible to use it for estimation of the gross carbon assimilation of olive in a given climate, if the water available for transpiration is known.…”

The leaf gas exchange of mature olive trees ( Olea europaea L.) was characterized over a wide range of water deficits in the field during 1998, in Cordoba, Spain. Leaf photosynthesis ( A ) and stomatal conductance ( g l ) responded diurnally and seasonally to variations in tree water status and evaporative demand. In the absence of water stress, A and g l were generally high during autumn and low in days of high vapour pressure deficits (VPD). Leaf A varied between 0 and 2 µ µ µ µ mol m

“…2), which was previously reported (Larcher et al, 1981;Abril and Hanano, 1998). This might be owing to the strong dependence of these characteristics on stomatal conductance, which was shown by a more close correlation of P n with g s than with C leaf (Figs.…”

“…Several studies have analysed photosynthetic recovery upon re-watering after a water stress period (Larcher et al, 1981;Castrillo & Calcagno, 1989;van Rensburg & Krüger, 1993;Giardi et al, 1996;Flexas et al, 1999;Marron et al, 2002;Thimmanaik et al, 2002). However, a systematic analysis, including amount and velocity of recovery starting at different water stress intensities and in different plant species, is still lacking.…”

Photosynthetic down-regulation and/or inhibition under water stress conditions are determinants for plant growth, survival and yield in drought-prone areas. Current knowledge about the sequence of metabolic events that leads to complete inhibition of photosynthesis under severe water stress is reviewed. An analysis of published data reveals that a key regulatory role for Rubisco in photosynthesis is improbable under water stress conditions. By contrast, the little data available for other Calvin cycle enzymes suggest the possibility of a key regulatory role for some enzymes involved in the regeneration of RuBP. There are insufficient data to determine the role of photophosphorylation.Several important gaps in our knowledge of this field are highlighted. The most important is the remarkable scarcity of data about the regulation/inhibition of photosynthetic enzymes other than Rubisco under water stress. Consequently, new experiments are urgently needed to improve our current understanding of photosynthetic down-regulation under water stress. A second gap is the lack of knowledge of photosynthetic recovery after irrigation of plants which have been subjected to different stages of water stress. This knowledge is necessary in order to match physiological down-regulation by water stress with controlled irrigation programmes.
