Abstract

The purpose of this study was to look at the frequency of infection and percent root infection of vesiculararbuscular mycorrhizae present in saplings of Sapium glandulosum in pasture and gaps. Saplings in the pasture had a significantly higher frequency of infection than saplings in the gaps (Two-by-two contingency table, X² = 27.855, p < 0.0001). Saplings in the pasture also had a significantly higher mean percent infection than saplings in the gaps (Mann-Whitney U test, U = 370.00, tied p-value = 0.0013). These findings indicated that the amount of disturbance that an area has been subjected to strongly influences the levels of VAM growth on S. glandulosum. El propósito de este estudio fue mirar las frecuencias del porcentaje de infección de las raíces de vesicular-arbuscular micorriza presente en los arbolitos de Sapium glandulosum que están en el pasto y los claros del bosque. Los arbolitos del pasto tenían una frecuencia de infección que estaba significativamente mas alta que los arbolitos en los claros (Dos-por-dos contingency table, X² = 27.855, p < 0.0001). Arbolitos del pasto también tenían un medio porcentaje de infección que estaba significativamente mas alto que los arbolitos de los claros (Mann-Whitney U examen, U = 370.00, tied pvalue = 0.0013). Estas conclusiones indican que el nivel de la alteración que una area se ha sometido tiene mucha influencia sobre los niveles de vesicular-arbuscular micorriza presente en S. glandulosum.
