Influence of the prescribed burning in species of ectomicorrizic mushrooms in natural forest of Pinus cubensis griseb.

Abstract

Evaluation of the influence of prescribed burnings in species of ectomicorrizic mushrooms in natural forest of P. cubensis. Burnings were applied in three parcels of 1000 m², using the method of the parcel of 1m² determining the quantity of available combustible material, being subdivided in 6 parcels of 500m², registering all the individuals one before day and starting from two later weeks to the burnings day, with 9 repetitions, interval of collection of mushrooms of two weeks. The combustible material showed a reduction total average in the area of a 58,44%. The parameters of the behavior of the fire were inside the established ranges of 145,04 Kcal/m/s¹. In the ectomicorrizic mushrooms were registered 7 species before burnings, after that, the first individuals appear, maintaining a stable increment in the successive thing, until surpassing the initial values of mushrooms.
