As part of the Competition for the co-financing of Croatian-Slovenian scientific research projects for the period 2023-2025, the project “Grapevine, viruses and mycorrhizal fungi – analysis of the complex interplay” was accepted. The leaders are collaborators on the Myco Grape project: Ph.D. Katarina Hancevic from the Croatian side and assistant. Ph.D. Matevž Likar from the Slovenian side. The main goal is to continue and improve the cooperation between the two teams through mutual visits and training, during which they will jointly work on the application of various statistical methods in a detailed analysis of the relationship between the grapevine, pathogenic and beneficial microorganisms.
