Abstract

Background and AimsIntercropping of truffle-producing trees with aromatic plants is used to improve profitability of truffle orchards during the initial 4-7 years. However, after that period the viability of this system is challenged by the appearance of brules, an area around host tree characterised by scarce plant cover where the fungus exhibits allelopathic activity. We aimed to investigate the ecological interactions between these crops and between their associated mycorrhizal fungi in adult truffle plantations.MethodsWe simulated two intercropping systems, truffle oak - lavender and truffle oak - rosemary in their adult stage. We analysed and compared aromatic plants and soil samples inside and outside the brules during the first year of the aromatic plants in the field.ResultsWe found a strong negative relation of brules with the growth of the aromatic plants, although not a decrease in the arbuscular mycorrhizal colonization of their roots. The essential oil yield and composition of aromatic plants was affected by brules. The extraradical truffle mycelium was not significantly affected by the presence of aromatic plants.ConclusionsThe growth and yield of aromatic plants was impaired during their first year growing in brules, whereas no negative effect of aromatic plants on truffle fruiting potential was found. The study improves our understanding of the mechanisms influencing the viability of the truffle tree - aromatic plant intercropping and the possible technical challenges.
