Different tree fruit loads and intensities of winter pruning were combined in an early-maturing peach cultivar 'Alexandra', sensitive to biennial bearing, so as to assess the impact of the number of fruit per meter shoot length on the regularity of fruit production. Crop load was shown to vary in the next year from a factor of one to a factor of 11...
Le concept Salsa vise à concevoir un arbre à multiple axes sur lequel les branches se développent autour du tronc initial pour former des "semi-troncs".
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...
This article presents QualiTree, a generic fruit tree model that can simulate the effects of various cultivation practices on the development and within-tree variability of fruit quality. These practices include fruit thinning, summer and winter pruning, irrigation and tree training. Combining both agronomic and physiology viewpoints, the model des...
Recent European incentive policies clearly targeted decreasing pesticide use in all agricultural systems as a key option to reduce environmental hazards and health risks. To reduce pesticide use is challenging in orchards where pesticides are recurrently applied to control numerous pests and diseases, but crucial to improve fruit production sustain...
Apple fruit is well known for its health properties, ascribed to its content in both phenolics and fibres. As more and more apples are consumed after processing, there is a need to understand the impact of the conventional process on the nutritional potential of applesauce. We have investigated the variation in composition between fresh and process...
In gene-for-gene host–enemy interactions, monogenic plant resistance results from pathogen recognition that initiates the induction of plant defense responses. Schematically, as the result of the on/off process of recognition, phenotypic variability in enemy virulence is expected to be qualitative, with either a failure or a success of host coloniz...
In this paper, QualiTree, a fruit tree model designed to study the management of fruit quality, and developed and described in a companion paper (Lescourret et al. in Trees Struct Funct, 2010), was combined with a simple light-interception sub-model, and then parameterised and tested on peach in different situations. Simulation outputs displayed fa...

The method presented here is fast and economical. The DNA obtained is of high quality, with a low level of cytoplasmic DNA contamination, and very efficient for the construction of sequencing libraries.
