“…It is suggested that leaf physiology could sensitively react even on a scale of minutes or hours, such as photosynthetic chemistry (Callaway et al 2003;Alongi 2008). Our study found that the plasticity of allocation and leaf morphology were quite similar among plant functional types in consistent with conclusions of other studies (Navas and Garnier 2002;Zunzunegui et al 2009). Therefore, a hierarchy of plasticity was outlined in the sequence of leaf physiology, whole-plant growth, leaf morphology and biomass ratios, and lastly the anatomical traits on the basis of their grand plasticity.…”

“…That means that the ranking of traits plasticity to one kind resource depends on supply of other resources. This ranking of traits plasticity was also partly summarized on shrub seedlings by Zunzunegui et al (2009). Plant plasticity differs among traits and levels of resources (Valladares et al 2006).…”

“…Zunzunegui et al (2009) reported that physiological traits of a semi-deciduous shrub were more plastic than allocation traits. According to the results of Lei et al (2006), growth of Populus przewalskii is more plastic than allocation in responses to water availability, but its physiological plasticity varies between populations.…”

This study aimed to investigate plasticity of different plant traits to varied light and water availability. A greenhouse experiment was conducted with Quercus aliena seedlings with two light and four soil water levels. Plant traits related to leaf physiology, morphology, anatomy, and biomass production were determined. The results showed that plant size had significant effects on leaf area, leaf number, shoot height, basal diameter and crown area. After excluding the influence of plant size, water treatment had stronger effects on plants compared to light levels, and their interaction effect was significant. The limited water supply significantly inhibited leaf photosynthetic rate and the fluorescence efficiency under high light. However, leaves submitted to moderate drought stress showed enhanced fluorescence activity under shade condition. Grand plasticity of leaf physiology and growth was the highest, followed by biomass allocation and leaf morphology, and lastly anatomy, and this ranking did not change as resources considered. Among the variables, leaf petiole length, chlorophyll content and leaf area could be selected as candidates for estimation of species' plasticity to water, light and their interaction, respectively. Therefore, our results suggested that there was a hierarchy existing among traits plasticity in Q. aliena, and supported the aboveground facilitation hypothesis that shade could alleviate the adverse effect of drought.

“…This result is also attested by the results of the correspondence analysis (CA). PI p is also linked to an enhanced capacity to colonize gaps and open areas (VALLADARES et al 2002, NIINEMETS andVALLADARES 2004) because it ensures adjustments of gas exchange in response to stress factors changes in the short term (ZUNZUNEGUI et al 2009). A high physiological plasticity allows species to achieve rapid growth increasing the capability to colonize early successional habitats (WALTERS and REICH 1999).…”

-Leaf trait variations in fi ve deciduous species (Quercus robur, Corylus avellana, Populus alba, Acer campestre, Robinia pseudoacacia) growing in an old broadleaf deciduous forest in response to light variation within the tree crown was analyzed. Net photosynthetic rate (P N ), leaf respiration rate (R) and the photosynthetic nitrogen use efficiency were, on average, more than 100% higher in sun than in shade leaves. A. campestre and C. avellana sun leaves had the highest specifi c leaf area (SLA, 156.0 ± 17.9 cm 2 g -1 ) and the lowest total leaf thickness (L, 101.9 ± 8.8 μm) underlining their shade-tolerance. Among the shade-intolerant species (Q. robur, P. alba and R. pseudoacacia), Q. robur had the lowest SLA and the highest L in sun leaves (130.6 ± 10.0 cm 2 g -1 and 160.8 ± 9.6 μm, respectively) since shade-intolerant species typically have thicker leaves. The higher P N decrease in respect to R decrease from sun to shade leaves attested the higher sensitivity of P N than R to light variations within the crown. This determined a 69% lower R/P N in sun than in shade leaves. This result is further attested by the signifi cant correlation between P N and the relative photosynthetic photon fl ux density. The shade-tolerant species have a 76% higher R/P N ratio than the shade-intolerant ones. The measured leaf phenotypic plasticity (PI = 0.35) was in the range of broadleaf deciduous species. Plasticity is a key trait useful to quantify plant response to environmental stimuli. It is defined as the ability of a genotype to produce different phenotypes depending on the environment. Among the considered species, Q. robur showed the highest PI (0.39) and P. alba the lowest (0.29). Knowledge on phenotypic plasticity is important in making hypotheses about the dynamics of the studied forest in consideration of environmental stress factors, including invasive species competition and global climate change.Keywords: deciduous trees, forest, gas exchange, light gradient, shade tolerance, specifi c leaf area * Corresponding author, e-mail: rosangela.catoni@uniroma1.it Unauthenticated Download Date | 5/13/18 5:24 AM CATONI R., GRATANI L., SARTORI F., VARONE L., GRANATA M.

“…Halimium halimifolium (Cistaceae) has been used in Doñana area as a scrub reference species because it can grow on varied environments from dune ridges to temporary flooded areas. Detailed physiological and morphological studies revealed the plasticity of H. halimifolium responses to contrasted rainfall patterns in dry and wet environments (Zunzunegui et al 2009). A study of the seasonal variation in ecophysiological traits and recuperation ability following summer stress in co-occurring species forming dry and wet communities, has not been carried out in field conditions.…”

Under natural conditions the overlapping of multiple stressors may initiate coordinated ecophysiological responses in Mediterranean species. Seasonal plasticity may enable plants to better cope with adverse environmental conditions and/or resource variability. In this article, we study the seasonal responses of 12 woody species in two sites of differing water availability, in a Mediterranean-type climate. Plants were measured for water potential, photochemical efficiency, photosynthetic pigments and leaf proline content throughout the year. The results revealed that species presented different ecophysiological strategies, even when sharing the same area. In the xerophytic site, some species suffered severe water stress (-12 MPa and F v /F m lower than 0.3), while others exhibited optimal values of F v /F m and only moderate water stress. All the plants recovered after the first autumn rains. In the hygrophytic site, some sclerophyll species did not exhibit signs of water stress, but did suffer photoinhibition in clear winter days. A plasticity index was calculated to provide an integrated value of species plasticity. In summer, plasticity was higher in the xerophytic site, while in winter it was higher in the hygrophytic site. Ordination analysis of the physiological traits supports the traditional gradient of Mediterranean strategies from drought semideciduous to evergreen sclerophyll species, although spiny legume species formed an independent functional group. The functional responses of species clearly differ among plant communities according to the prevailing site stressors, but no unique pattern emerges. Species combine traits in broader strategies according to previous evolutionary story exhibiting a certain amount of trade among traits, each contributing to alleviate a part of the plant stress.
