En France, les productions fruitières et légumières qui occupent moins de 2% de la SAU sont caractérisés par la diversité des espèces cultivées et les multiples systèmes de culture qui peuvent avoir des impacts environnementaux divers. Face aux nouveaux enjeux de développement d’une horticulture sensu lato à haute performance environnementale, l’In...
La résistance génétiquement déterminée des plantes est un moyen efficace et respectueux de l’environnement de lutter contre les pucerons. Cependant, des biotypes de pucerons, capables de contourner les résistances, sont apparus dans plusieurs systèmes plantes–pucerons. Dans cet article, sur les bases génétiques et moléculaires des résistances aux p...
No valuable source of resistance to Plum pox virus (PPV), the causative agent of sharka disease, has been found in peach (Prunus persica), but polygenic resistance to PPV was described in Prunus davidiana clone P1908. Two previous studies using F1 and F2 populations derived from the nectarine cv. Summergrand and P. davidiana P1908 identified a tota...
Conventional agriculture is based on a high level of chemical inputs such as pesticides and fertilisers, leading to serious environmental impacts, health risks and loss of biodiversity in agrosystems. The reduction of pesticide use is a priority for intensively sprayed agricultural systems such as orchards. The preservation and promotion of biodive...

Cacopsylla pruni is the vector of European stone fruit yellows, a quarantine disease of Prunus trees. Nine polymorphic microsatellite markers were developed from enriched DNA libraries. Allelic variability was assessed in a collection of 149 females obtained from five localities covering a large geographical area in France. The number of detected a...
Irrigation and fertilisation were recently considered as useful tools to control tree shape, and reduce pruning costs. The role of the N reserves, which determined spring growth, was considered to be essential. We intended therefore to evaluate its effects on peach tree architecture. Four levels of N fertilisation were applied on 1-year-old trees, ...
