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).
We are back in-person! Join us for the annual NATGA Congress in October 2021 in Sonoma County, CA
Dwayne Tate of North Carolina Department of Agriculture & Consumer Service, Field Services will talk about the basic principles of liming and soil acidity.

We’re pleased to announce that dozens of growers have filled out the survey and the database is now growing. We are well on our way to answering a series of pressing questions for growers. Based upon the growers feedback we are launching a revised version that will be more user friendly. In addition we will be introducing the database website that will be accessible to all survey participants.

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
This project addresses a challenge in the truffle industry, specifically the detection and monitoring of truffle fungi during the many-year period of orchard establishment before truffles can be expected to start producing. The successful colonization of the host tree by a commercial truffle fungus and the retention and spread of that fungus on the roots are critical for successful orchard establishment, yet growers have limited tools to monitor and confirm this process. We adapted and developed reliable DNA extraction methods for orchard soil, DNA fingerprinting methods for the major commercial truffle species, and field sampling procedures for the detection and identification of truffle fungi in orchard soil.
