Biological cycle

If geo-climatic conditions are favourable, the spores spread in the ground close to symbiotic plants germinate by forming a number of hyphae. The latter, in contact with surrounding roots give life to mutually beneficial relationship with mycorrhiza — transmission system of substances with the plant roots from which, under ideal conditions of temperature and humidity, starts the mycelium.

This gives rise to the formation of fruiting body or carpoforo that maturing develops inside new spores and his strong and characteristic fragrance.

 

Thanks to the truffle, the nose becomes so actively sought and consumed by insects and animals, which through the digestive system will disseminate spores. A percentage of spread can also occur through dragging of water when the truffles are not collected and have undergone the decomposition stage.

Not always, however, the truffle complements its biological cycle. Many factors are in fact of adversity to its development.

Adversity

The main factors, atmospheric and physical, that can cause damage to the truffle are:
 
- drought or frost depths
 
- environmental pollution
 
- insects such as tsetse fly besides some truffle beetles
 
- symbiotic plant diseases such as white oak pain and insects like the Crisorrea and the Diaspari
 
Even animals that feed on this precious fungus are an adversity to its growth. At the same time, however, are the primary means for its dissemination.
