dc.description.abstractSe realizó un experimento en invernadero para determinar la dependencia micorrizal (dm) de laurel (Ocotea sp.). Para tal fin se utilizó un diseño experimental completamente al azar. Los tratamientos tuvieron un arreglo factorial 3x2 con cinco repeticiones, los cuales consistieron en la combinación de tres niveles de fósforo (P) en la solución del suelo (0.002, 0.02 y 0.2 mg L-1) y dos niveles de inoculación micorrizal (inoculado y no inoculado) con Glomus aggregatum Schenck Smith. Se emplearon como variables respuesta el contenido de P foliar en función del tiempo. Al momento de la cosecha, se determinaron la masa seca aérea, el P total absorbido en la parte aérea, la colonización micorrizal y la dm. Los resultados indican que en algunos días de muestreo el contenido de P foliar aumentó significativamente con la inoculación micorrizal en laurel al nivel de P en solución de 0.2 mg L-1 pero no en los otros niveles de P. El contenido de P total absorbido no incrementó significativamente. La dm fue del 28%, lo que permite clasificar esta especie como moderadamente dependiente.spa
dc.description.abstractA greenhouse experiment was carried out to determine the mycorrhizal dependency of laurel (Ocotea sp.). In order to do this, a completely randomized experimental design was used, with six treatments in a factorial array of 3x2 and five repetitions. The treatments involved a combination of three Phosphorus (P) levels in soil solution (0.002, 0.02 and 0.2 mg L-1) and two levels of mycorrhizal inoculation, either inoculated or non-inoculated with Glomus aggregatum Schenck Smith. The leaf P content as a function of time was used as an output variable. Shoot dry matter, shoot P content, mycorrhizal colonization of roots, and mycorrhizal dependence were measured at harvest. The results indicated that the leaf P content increased significantly when using the mycorrhizal inoculation in laurel at P level 0.2 mg L-1, but not in the other P levels, on some of the sampling days. Shoot dry weight and total plant P content did not increase at all levels of soil available P. Mycorrhizal dependency of laurel reached 28%, which allows this species to be classified as moderately dependenteng
