Resumen
SANTILLANA, N. y TORO, M.. Mycorrhizal arbuscular association in pastures of the High Andean Community of Ccarhuaccpampa - Aya cucho. Ecol. apl. [online]. 2018, vol.17, n.2, pp.165-169. ISSN 1726-2216. http://dx.doi.org/10.21704/rea.v17i2.1236.
The aim of this study was to determine the mycorrhizal status of four species of natural pastures of the community of Ccarhuaccpampa. The number of spores per 100 g of soil, the characterization of spores and the percentage of colonization of the roots were determined. The number of spores / 100 g of rhizospheric soil varied according to the plant species (66-732). Sixteen morphotypes of mycorrhizal fungi were located in three genera: Glomus, Acaulospora and Entrophospora, the first one was considered the most important because it had the highest number of morphotypes and was present in the different soils evaluated. A low mycorrhization of the analyzed roots was found (20 and 27%) and the presence of the arbuscular mycorrhizal association in all the species studied. A high correlation was determined between the number of spores per 100 g of soil and the percentage of mycorrhization of the roots, which indicated a similar tendency between both determinations.
