Abstract:
... BACKGROUND AND AIMS: Understanding plant adaptation to drought is a crucial challenge under climate change. This study aimed to investigate root traits and water use of grass populations exhibiting a range of dehydration avoidance and tolerance strategies to cope with drought. METHODS: Sixteen populations of the perennial grass Dactylis glomerata originating from three biogeographical origins (Nor ...

Abstract:
... AIM: Root growth strategies may be critical for seeding survival and establishment under dry conditions, but these strategies and their plasticity are little known. We aim to document the ability of young grass seedlings to adjust their root system architecture, root morphology and biomass allocation to roots to promote water uptake and survival under progressive drought. METHODS: Seedlings growin ...

Abstract:
... Roots help in soil water and nutrient uptake and provide carbon (C) input for soil C sequestration, but information on root biomass of bioenergy perennial grasses is lacking. Root/shoot ratios are used to estimate crop root biomass and C inputs, but the values for perennial grasses are also scanty. We examined root biomass, root/shoot ratios, and soil water contents to a depth of 120cm after grass ...

Abstract:
... Grasslands provide numerous ecosystem services but their sustainability is threatened by climate change. As plant functional diversity is expected to stabilize ecosystem functions, we tested whether mixing species with contrasting root systems could improve the resilience of Mediterranean grasslands under increasing aridity. We hypothesized that root functional identity (RFI) and diversity (RFD) r ...

Abstract:
... Grass swards are increasingly used in vineyards to improve ecosystem function, reduce vine vigor, and enhance grape (Vitis vinifera L.) quality. In Mediterranean rainfed vineyards, the use of intercropping has been constrained because of excessive competition for water with the vine over summer. We aimed to test cultivars of Mediterranean forage grasses with a range of summer dormancy, which confe ...
