Summary:
Researchers at the Botany Department of the University of Navarra, Ana María de Miguel y Miriam de Román, have undertaken a study on the use of mycorrhizzae-introduced plants (colonised with the Tuber melanosporum fungus or black Perigord truffle), on surface land areas affected by fires.

Taking advantage of reforestation work carriedout by Viveros y Repoblaciones de Navarra in the recovery of the Nazarkermes oak forest (Estella-Lizarra region), a typicalMediterranean-type ecosystem found in the Navarre region, the twoexperts compared the progress of the plants’ survival with the presenceor otherwise of the mycorrhizzae. Mycorrhizzae are the product of thefungus-plant symbiosis produced at the roots of the trees, facilitatingthe growth of the truffle at a par with that of the plant.

Afterthree years of research, they concluded that the kermes oaks exposed toT. melanosporum mycorrhizzae show a greater rate of survival than thoseplanted without mycorrhizzae, when dealing with land suitable for thecultivation of the truffle. Thus, environmental advantages are added tothe economic boost in those areas suitable for truffles.

The twobotanists have pointed out the lack of research in this field ofdeteriorated land areas of the Mediterranean, investigations that couldbe of great use. They also emphasise the value of the use mycorrhizzaein reforestation, given that it favours growth of trees and theirresistance to diseases.
