Presencia de hongos micorrízico arbusculares en tres áreas de intervención antrópica en la vereda Albania del municipio Tibacuy-Cundinamarca

Abstract

Over the years it has been determined that the study of mycorrhizae is of great importance, since they perform a symbiosis with the plants benefiting them; supplying them with nutrients that are limited by site conditions, water absorption, disease protection and drought resistance and salinization according to this, it is essential to understand the soil-plant relationship and observe the interactions that occur there. Having the presence of areas intervened in the sidewalk of Albania-Tibacuy and considering that the influence of microorganisms (HMA) contributes to and improves productivity (Hart and Forsythe, 2012) and soil status, in this paper we try to show the relationship between the presence of AMF in three areas with degree of anthropic intervention (guadual, coffee and secondary forest) evaluating spore density with respect to different physical-chemical factors of the soil, quantification of colonization of arbuscular mycorrhizal fungi in the root system and observing the morphotypes present in the different areas; For this, a statistical analysis was carried out where, by means of the R3.4.1 program, the differences between the three study areas with respect to the evaluated variables were determined; For this, the non-parametric Kruskall Wallis comparison test was applied for independent samples with a level of significance of 95%. In addition, representative graphs such as bar graphs and PCA-Biplot, made using the R 3.4.1 and Excel 2010 program, were made a variation in the amount of spores in the three areas, presence of colonization in the root system, differentiation in the amount of spores with respect to the physical-chemical characteristics of the soil and different morphotypes in the areas evaluated.
