- W2749333067 abstract "abstract Inmanyregionsoftheworld,suchasSouthernEuropeandmostMediterraneanareas,thefrequencyandmagnitudeofdroughtsandheatwavesareexpectedtoincreaseunderglobalwarmingandwillchallengethesustainabilityofbothnativeandsowngrasslands.Toanalyzetheadaptivestrategiesofspecies,geno-types and cultivars, we aim both (i) to understand the composition and functioning of natural grasslandsand (ii) to propose ideotypes of cultivars and optimal composition for mixtures of species/genotypesunder water deficit and high temperatures. This review presents a conceptual framework to analyzeadaptive responses of perennial herbaceous species, starting from resistance to moderate drought withgrowthmaintenance(dehydrationavoidanceandtoleranceoflamina)togrowthcessationandsurvivalofplantsunderseverestress(dehydrationavoidanceandtoleranceofmeristems).Themostdiscriminatingfunctional traits vary according to these contrasting strategies because of a trade-off between resis-tance to moderate moisture deficit and survival of intense drought. Consequently it is crucial to measurethe traits of interest in the right organs and as a function of soil water use, in order to avoid misleadinginterpretationsofplantresponses.Furthermore,collaborationbetweenecologists,eco-physiologists,andagronomists is required to study the combination of plant strategies in natural grasslands as only thiswill provide the necessary rules for species and cultivars or ecotypes assemblage. This ‘agro-ecological’approach aims to identify and enhance functional complementarity and limit competition within themulti-specific or multi-genotypic material associated in mixtures since using plant biodiversity shouldcontribute to improving grassland resistance and resilience.© 2013 Elsevier B.V.
