Introduction et dispersion d'une espèce envahissante : le cas de l'ambroisie à feuilles d'armoise (Ambrosia artemisiifolia L.) en France

2011

National audience; Ambrosia artemisiifolia L. (common ragweed) was accidentally introduced into France in the 1860s. Its single vector of introduction in Europe was red clover seeds (Trifolium pratense L.), probably coming from Pennsylvania, United States at the time. A. artemisiifolia was later introduced into France in many places and at different times. This species has no natural or effective seed dispersal mechanisms and the spread of this weed in the territory is ensured by human activities that carry the seeds and create disturbed environments favourable to its development. It is now established in the Rhone Valley and a number of different factors (cropping system evolution, climate…

Dynamique spatio-temporelle des communautés végétales dans les agro-écosystèmes

2014

National audience; Identifier les déterminants de la structuration des communautés adventices est une question cruciale en agro-écologie, au vu des différentes fonctionnalités de cette flore dans l’agro-écosystème – un impact potentiellement négatif sur le rendement agricole mais aussi une valeur de nature patrimoniale comme fonctionnelle, en tant que base de nombreuses chaines trophiques en milieu agricole. En réponse à des moyens de lutte chimique efficaces, la flore adventice a largement décliné au cours des dernières décennies et reste aujourd’hui soumise à des pressions anthropiques récurrentes qui affectent la distribution spatiale des communautés dans la mosaïque agricole. A l’échell…

Analyse des effets direct et indirect des pratiques agricoles sur les adventices et la production de blé tendre d’hiver

2016

Analysis of direct and indirect effects of farming practices on weeds and winter wheat yield. Farmers implement farming practices to maximize production by limiting biotic (e.g. weeds) and abiotic (e.g. nutrient) growth factors. Our study aimed to quantify direct and indirect (through a change of weed pressure) effects of farming practices on yield. We analysed the relationships between farming practices, weeds and yield of 152 wheat fields located in the study site of Fénay (UMR Agroécologie, Dijon) using partial least square path modelling (PLS-PM). Our results showed that farming practices had a positive direct effect on crop productivity (β = 0.32). Farming practices decreased weed pres…

Trait distribution within winter wheat fields can partly be explained by disturbances and competition for resources

2013

International audience; Weed species are not homogeneously distributed into field elements (Cordeau et al. 2012)*.In a field, weed species are mainly competing with the crop and constrained by management practice (i.e.disturbances). In the crop edge, less unfavorable conditions for weed development (i.e.absence of direct crop competition,l ess frequent disturbances could explain the greater diversity of weeds.To understand this observation, a functional approach base dont raits known to respond both to disturbances and to competitive or facilitative interactions can be used.Our assumptions are that(i)the crop edge is likely to all owawi derrange of ecological strategies thus promoting speci…

2013

National audience; Un champ cultivé est subdivisé en un ensemble de compartiments : l’interface (zone labourée mais non semée), le bord de champ (premiers rangs de la culture) et le plein champ. L’interface est connue pour présenter une diversité taxonomique plus élevée et se caractérise par des filtres environnementaux moins contraignants : faible perturbation (fauche essentiellement) et faible compétition pour les ressources (lumière notamment). Afin de mieux comprendre l’effet de filtrage des différents compartiments d’un champ sur la structuration des communautés adventices, une approche fonctionnelle a été privilégiée. Dans cette étude, nous nous sommes intéressés à : (i) connaître la …

Mutant ACCase alleles endowing herbicide resistance have a direct effect on seed germination

2013

Germination and emergence dynamics and herbicide resistance are adaptive traits crucial for weed persistence in arable fields. Herbicide resistance alleles can have pleiotropic effects on other traits. We investigated the pleiotropic effects of acetyl-coenzyme A carboxylase (ACCase) alleles L1781, N2041 or G2078 on seed germination and seedling emergence in the grass weed Alopecurus myosuroides (black-grass). We used black-grass populations with homogenised genetic backgrounds that segregated for L1781, N2041 or G2078 ACCase alleles. In two series of experiments, germination dynamics and seedling growth were compared among seeds containing embryos carrying no, one or two copies of a given m…
