There is always a lot of discussion about consequences the concentration number grapevine varieties cultivated and decline in diversity plant material clones available from nurseries used by winegrowers. With aim to better understand define more precisely disadvantages or advantages different situations terms “cultivated biodiversity”, we sought develop indices adapted allowing compare neutral objective way these diverse situations. These indicators may concern geographical levels vineyards...
This study investigates whether ethanol (EtOH) modulates response to drought in grapevine, as demonstrated previously Arabidopsis, rice and wheat. We ran a potted-cutting experiment with progressive soil water deficit. Plants pre-treated 250 mM EtOH solutions exhibited slower depletion of the fraction transpirable (FTSW), compared controls. While decreased transpiration early days, these plants maintained higher leaf than controls after 10 days depletion. The FTSW threshold for process was...
Agrobiodiversity is a promising nature-based solution in the pursuit of sustainable agriculture. In wine-growing systems, commercial pressure and varietal regulations have narrowed agrobiodiversity vineyards despite higher diversity being an important buffer against effects climate change. If drivers grape change are well-understood at national to global scales, little known about local, past or anticipated trajectories that drive dynamics depending on growers’ cultural values, practices...
Abstract Studies suggest that ethanol (EtOH), triggers plant adaptation to various stresses at low concentrations (10 µM 10 mM). This study investigates whether EtOH induces drought acclimation in grapevine, as demonstrated previously Arabidopsis , rice, and wheat. Preliminary results with bare root Gamay cuttings showed those pre-treated aqueous solutions lost fewer leaves when deprived of water compared controls. Subsequently, we ran a potted-cutting experiment progressive soil deficit....
Today’s breeding efforts applied to grapevines are mainly focused on the use of resistance bio-aggressors, after beingmotivated, often unconsciously, for millennia by quantitative and qualitative concerns, adaptations environmentalconditions. Thanks advances in genomic knowledge molecular markers, it is now possible envisage more andmore solutions against different pathogens (fungi, bacteria, viruses, insects), near future, ensure durability ofthese resistances while combining them with...
Grapevine trunk diseases can infect nursery plants at different stages of propagation. Here, we evaluated the efficiency aqueous ozone against two fungi associated with (Phaeoacremonium minimum and Phaeomoniella chlamydospora). The effect on plant growth is also studied. Aqueous completely suppressed spore germination in vitro. In planta fungal development was reduced six weeks post-inoculation. nursery, treatment comparable to usual chemical treatment. Irrigation had no negative effects...
<p style="text-align: justify;"><strong>Aim</strong>: Few recent studies have been investigating the effect of clone on aroma compounds. The aim this research work was to study impact certified clones from <em>Vitis vinifera </em>L. cv. Duras N grape quality and rotundone, a sesquiterpene responsible for peppery which has reported recently in red wines made cultivar.</p><p justify;"><strong>Methods results</strong>: experimental site...
Aim: Rotundone and 3-isobutyl-2-methoxypyrazine (IBMP) are two potent aroma compounds responsible for pepper bell notes in red wines, respectively. The aim of the study was to modulate, through common viticultural practices, volatile composition these molecules Fer wines from a temperate climate wine region with very cool nights, located southwest France.Methods results: Three practices (leaf removal 10 days after berry set, lateral shoots, delayed harvest 7 control) were investigated 2015...
Wine grape breeding for fungal resistance has been very dynamic worldwide over the last decade. The quick phenotyping of genotype quality traits, including aroma composition, remains challenging. Selected ion flow tube mass spectrometry (SIFT-MS) could be particularly valuable this usage. Due to high number seedlings phenotype and low availability berries, sampling strategy can hardly rely on time-consuming destructive methods such as measurement classical maturity parameters (i.e., sugar...
