The ability of three Mediterranean oaks (Quercus coccifera L., Quercus ilex ssp. ballota (Desf.) Samp and Quercus suber L.) to cope with intense drought was investigated. Water stress reduced stomatal conductance and photosynthesis in these species. Drought-mediated changes in photosynthetic-related parameters allowed the characterisation of the specific photo-protective mechanisms. Specifically, Q. suber downregulated photosynthetic electron transport rates (ETR) closing PSII reaction centres…

High-salinity activates photoprotective mechanisms in Quercus suber via accumulation of carbohydrates and involvement of non-enzymatic and enzymatic antioxidant pathways

Cork oak (Quercus suber), native to Mediterranean areas, is a plant of ecological and economical relevance, nevertheless, the effects of soil salinization on this species are currently unknown. We

Cavitation Limits the Recovery of Gas Exchange after Severe Drought Stress in Holm Oak (Quercus ilex L.)

Holm oak (Quercus ilex L.) is a Mediterranean species that can withstand intense summer drought through a high resistance to cavitation far beyond the stomatal closure. Besides stomatal limitations,

Leaf functional plasticity decreases the water consumption without further consequences for carbon uptake in Quercus coccifera L. under Mediterranean conditions.

The results suggest that Quercus coccifera does not always use the main resources at leaf level as efficiently as possible, and cannot overcome the morpho-functional constraints that limit photosynthetic activity, even under potentially favourable conditions.

Quantification of leaf-scale light energy allocation and photoprotection processes in a Mediterranean pine forest under extensive seasonal drought.

The response of CO2 assimilation and photoprotection strategies to stomatal conductance and leaf water potential appeared independent of whether stress was due to atmospheric or soil water deficits across seasons and treatments.

Contrasting functional strategies following severe drought in two Mediterranean oaks with different leaf habit: Quercus faginea and Quercus ilex subsp. rotundifolia.

The progressive imposition of water stress evidenced that both types of Mediterranean oaks displayed different functional strategies to cope with water limitations, and the decrease in mesophyll conductance associated to edaphic drought seems to be the main factor explaining the differences found in the dynamics of net CO2 assimilation throughout the drought period.

Are symplast tolerance to intense drought conditions and xylem vulnerability to cavitation coordinated? An integrated analysis of photosynthetic, hydraulic and leaf level processes in two Mediterranean drought-resistant species

In the last decades, plant resistance to drought conditions has been studied intensively both at wholetree level and at tissue level. These studies have highlighted the role of xylem cavitation in



Comparative ecophysiological effects of drought on seedlings of the Mediterranean water-saver Pinus halepensis and water-spenders Quercus coccifera and Quercus ilex

Ecophysiological and structural traits of seedlings of the water-saver Pinus halepensis and the water-spenders Quercus coccifera and Q. ilex were studied in response to water stress under greenhouse

Seasonal changes in photosynthesis and photoprotection in a Quercus ilex subsp. ballota woodland located in its upper altitudinal extreme in the Iberian Peninsula.

Overall, the data indicate down-regulation of photosynthesis during the summer, with decreases in maximum potential PSII efficiency, actual and intrinsic PSII efficiencies, photochemical quenching and increases in NPQ.

Differences in the response of carbon assimilation to summer stress (water deficits, high light and temperature) in four Mediterranean tree species

A high degree of co-ordination is apparent between stomatal behaviour, photosynthetic capacity and photoprotection mechanisms in trees during the summer in Portugal.

Trichomes and photosynthetic pigment composition changes: responses of Quercus ilex subsp. ballota (Desf.) Samp. and Quercus coccifera L. to Mediterranean stress conditions

Comparing leaf optical properties, photosynthetic pigment composition and photosystem II efficiency of two Mediterranean Quercus species revealed different patterns of response of Q. ilex subsp.

Effects of severe dehydration on leaf photosynthesis in Quercus petraea (Matt.) Liebl.: photosystem II efficiency, photochemical and nonphotochemical fluorescence quenching and electrolyte leakage.

The photosynthetic apparatus of Q. petraea is rather insensitive to leaf dehydration per se during drought under natural conditions, and stability of F(v)/F(M) indicated that the functional integrity of PS II was not altered until D reached values above 0.75.

Photoprotective Function of Photorespiration in Several Grapevine Cultivars Under Drought Stress

Stomatal responses to drought at a Mediterranean site: a comparative study of co-occurring woody species differing in leaf longevity.

Stomatal responses to decreasing predawn water potential (Psipd) and increasing leaf-to-air water vapor pressure difference (VPD) of co-occurring woody Mediterranean species with contrasting leaf habits and growth form are studied to determine if stomatal sensitivity is related to differences in leaf life span and leaf habit.

Effects of drought on photosynthesis in grapevines under field conditions: an evaluation of stomatal and mesophyll limitations.

The apparent carboxylation efficiency and the compensation point for CO2 remained unchanged under severe drought when analysed on a Cc, rather than a Ci, basis, suggesting that previously reported metabolic impairment was probably due to decreased gmes.

Photochemistry, remotely sensed physiological reflectance index and de-epoxidation state of the xanthophyll cycle in Quercus coccifera under intense drought

It is concluded that PRI is a sensible, indirect, non-destructive water stress indicator, even in plants experiencing intense drought.

Comparative water relations of four Mediterranean oak species

The water relations and responses of two evergreen (Quercus ilex L. and Q. suber L.) and two deciduous (S. afares Pomel. and Q. faginea Will.) Quercus species were studied under experimental
