CABiosE : Comparative Analyses of Biostimulant Effects on tomato crops and their associated microbiota, under water stress conditions.
Résumé
The CABiosE project investigates the effects of biostimulants (BS) on tomato crops and their associated microbiota under water stress conditions. Biostimulants are products that enhance plant development by improving nutrient assimilation or tolerance to abiotic stresses. The project aims to identify mechanisms induced by BS in plants, their role in improving resilience to water stress, and their influence on rhizosphere and phyllosphere microbiota. Initial trials screened seven BS, selecting two (M6 & M7) for further study based on their effects on fruit production and plant growth under stress. Future steps include deeper investigations into BS effects on young plants, microbiota, and fruit development, as well as trials in production conditions to evaluate yield and quality. The research seeks to understand BS modes of action, variability in effectiveness, and provide recommendations for farmers facing water shortages. Results may lead to innovative tools for assessing BS efficacy and new experimental guidelines for registration dossiers.
