Resumen

La reproduccio?n de enzimas extracelulares por las ectomicorrizas moviliza una fraccio?n importante de los compuestos presentes en el suelo. Se presentan resultados de las actividades enzima?ticas relacionadas con la movilizacio?n de nitro?geno y fo?sforo para cuatro especies de hongos formadores de ectomicorrizas, Suillus luteus (L.: Fr.) F. Gray, Xerocomus badius (Fr.:Fr.) Gilbert, Boletus pinicola (Vitt.) Venturi y Pisolithus tinctorius (Pers.) Coker & Couch. Se considera el valor potencial de las actividades enzima?ticas como criterio en la seleccio?n de hongos inoculantes. Los valores altos suponen una mayor utilidad de los hongos corno inoculantes en condiciones de vivero.
