Keynote presentation by Peter Sourzat at the 2021 NATGA Fall Congress
Study on the impact of irrigation treatments on the association of black truffle presented by Becky Loverock at the NATGA Fall Congress 2021
The gastronomic relevance and price of truffles are related mainly to its unique aroma. In this study, we explore the impact that different volatile compounds have on the aroma quality of fresh truffles using gas chromatography-mass spectrometry (GC-MS).
The objective of my presentation is to illustrate several researches on truffle life cycle and truffle cultivation developed in France. I will briefly present our knowledge on the sexual reproduction of the black truffle and then I will highlight the main results of the national research program CulturTruf. In this project we have experimented with watering truffle beds by monitoring the soil water potential (SWP) and have shown that this improves truffle production. I will show how we have developed an innovation (pF Tracer) allowing truffle growers to equip themselves with probes to follow the pF. Finally, I will present our latest remarkable results on the culture of the white truffle Tuber magnatum.
Watering, mulching and shadowing in Tuber melanosporum and Tuber aestivum orchards – Detail coming soon
i F o r e s t: Biogeosciences and Forestry, Research Article: True truffles in the genus Tuber are the most valuable ectomycorrhizal fungi and their cultivation has become widespread around the world. Competition with other ectomycorrhizal fungi and especially with undesired Tuber species
A quality grading system developed using sensory technology and based on chemical signatures (aroma profiles) is proposed to underpin the current truffle grading standards employed by the Australian Truffle Industry.
Black truffle (Tuber melanosporum) is a highly-appreciated fungus that grows below ground during several months, undergoing a series of morphogenetic stages before it is harvested in late autumn or winter. Black truffle production in Spain has been subject to important temporal variation in recent decades.
In Tuber melanosporum cultivation, fruitbody traits are gaining relevance due to their increasing prominence on prices. We investigated the edaphic and temporal patterns of fruitbody traits and characterised the efect of trufe nests (localised peat-based amendment supplemented with T. melanosporum spores) on traits.
