Condiciones edáficas, abundancia y riqueza de hongos ectomicorrizógenos comestibles

Abstract

Los hongos ectomicorrizógenos (HECM) favorecen la movilización nutrimental y el transporte del agua entre el sustrato y los árboles, por lo que la asociación ectomicorrícica es fundamental para el buen desarrollo de los ecosistemas forestales. Para establecer los efectos de las propiedades edáficas en la riqueza y abundancia de las poblaciones de HECM, se compararon cuatro tipos de prácticas silvícolas: corta de regeneración, de aclareo (primera y segunda) y de liberación. Se delimitaron y georreferenciaron 10 parcelas de monitoreo, en bosques bajo aprovechamiento del municipio Zacatlán, Puebla. La riqueza y la abundancia fúngica se evaluaron en 2015 y 2016; en este último, se hizo el muestreo y análisis del suelo. Se obtuvieron diferencias significativas entre años para la abundancia en la segunda corta de aclareo y en la de liberación, así como entre las cortas de aclareo que responden al periodo entre el año de intervención y el de muestreo. El porcentaje de materia orgánica y de arena registraron una correlación positiva con la abundancia, en contraste con K, Ca, Mn y Mg, que fueron negativas entre tratamientos, y no se obtuvieron diferencias para pH y la riqueza de especies; sin embargo, Lactarius indigo, Boletus aestivalis y Tylopilus sp. solo se recolectaron en rodales con valores de 5.76 a 5.93, en las parcelas de cortas de aclareo y liberación. Los resultados muestran que las prácticas silvícolas afectan el área basal arbórea alterando las propiedades químicas y físicas del suelo, lo que a su vez incide sobre la abundancia de esporomas.
