Summary in the original language of the document
Cette étude vise à évaluer l’effet bénéfique de la biotisation pour favoriser la croissance et améliorer la production de cultures de fraisiers en sol. Trois micro-organismes (une souche de Fusarium oxysporum non pathogène Fo47, une souche de Pseudomonas fluorescens A6, une espèce de champignon endomycorhizogène Glomus intraradices) sont incorporés en combinaisons binaires dans le substrat d’acclimatation des plantules. Après quatre semaines, les plantes sont transplantées dans quatre sols différents. Les analyses microbiologiques montrent la bonne installation de Fo47 et P.f. A6 dans les quatre sols naturels. Aucun effet négatif de la co-inoculation n’est observé. Une augmentation non significative de la production est observée pour les fraisiers biotisés, en particulier dans un des sols répertorié comme fatigué.
Summary translation
The aim of this study was to evaluate the beneficial effect of biotization on plant protection against root disease and to improve yield of strawberry in field conditions. Three micro-organisms (a non-pathogenic strain of Fusarium oxysporum Fo47, a strain of Pseudomonas fluorescens (A6) and the arbuscular mycorrhizal fungus Glomus intraradices) were introduced in binary combinations into the weaning peat substrate. Four weeks after acclimatization, the plants were transplanted in four fields. Microbial analysis showed that both Fo47 and P.f. A6 established well in these four natural soils. There was no negative interaction of the co-inoculation. A tendancy of increased yield was observed in biotized plants, especially in one field known to present soil sickness.
