Differential warming at crown scale impact walnut primary growth onset and secondary growth rate Open

Nicolas Dusart, Bruno Moulia, Marc Saudreau, C. Serre, Guillaume Charrier , et al. · 2024

Trees are exposed to significant spatio-temporal thermal variations, which can induce intracrown discrepancies in the onset and dynamics of primary and secondary growth. In recent decades, an increase in late winter and early spring temper…

On the mechanism for winter stem pressure build-up in walnut trees Open

Cyril Bozonnet, Marc Saudreau, Éric Badel, Guillaume Charrier, Thierry Améglio · 2024

Xylem embolism is a significant factor in tree mortality. Restoration of hydraulic conductivity after massive embolization of the vascular system requires the application of positive pressure to the vessels and/or the creation of new condu…

Freeze dehydration vs. supercooling in tree stems: physical and physiological modelling Open

Cyril Bozonnet, Marc Saudreau, Éric Badel, Thierry Améglio, Guillaume Charrier · 2023

Frost resistance is the major factor affecting the distribution of plant species at high latitude and elevation. The main effects of freeze-thaw cycles are damage to living cells and formation of gas embolism in tree xylem vessels. Lethal …

Protecting Apricot Orchards with Rain Shelters Reduces Twig Blight Damage Caused by Monilinia spp. and Makes It Possible to Reduce Fungicide Use Open

Laurent Brun, Freddy Combe, Christophe Gros, Pascal Walser, Marc Saudreau · 2023

Blossom and twig blight, caused by Monilinia spp., is the main disease in apricot trees. In this study, we installed transparent rain shelters in apricot orchards to study their influence on the modification of the microclimate at the leve…
