“…The Fe concentration in these species was much greater than concentrations reported for other tropical species growing under field conditions (Herbert and Schonau, 1991;Drechsel, 1992;Marenco et al, 2003). A significant reduction in pH might increase the localized availability of Fe for plants.…”

“…Among all the essential factors that stimulate the plant biomass accumulation, nutrient availability, nitrogen and phosphorus, and also water, are the most important ones (Marschner 1995;Marenco et al 2003). (F test, p<0.05) between organic compost and AMF on the shoot height of M. caesalpiniaefolia grown on mine spoil in the greenhouse (n=4).…”

The increasing number of degraded soil areas caused by open cast mining activities has brought about a critical damage to the environment. The mine spoil must be ameliorated with anthropogenic interferences which consist of revegetating soils after organic matter amendment and provision of microbial diversity, to guarantee basic conditions for a sustainable soil biological activity. Five woody species, Acacia mangium Willd., Inga edulis Mart., Mimosa caesalpiniaefolia Benth, Parkia multijuga Benth., and Schinus terebinthifolia Schlecht. & Cham were cultivated under greenhouse conditions to evaluate the potential of plant establishment on cassiterite mining waste, considering the contribution of mycorrhizal fungi inoculation, organic compost, and thermophosphate amendment. The shoot height, dry weight, and nitrogen and phosphorus shoot contents were determined. Three species of nodulating legumes, A. mangium, M. caesalpiniaefolia, and S. terebinthifolia showed a great positive response to organic compost, termophosphate, and mycorrhizal inoculation, increasing the plant height and the shoot dry weight. Plants inoculated with arbuscular mycorrhizal fungi and fertilized with organic compost also increased their nitrogen and phosphorus shoot contents. The addition of organic compost and mycorrhizal fungi were essential for plant development and the reforestation of mining areas should be initiated with mycotrophic and nodulating legumes.

“…Una alternativa de mitigación ha sido y sigue siendo la recuperación de ecosistemas a través de especies forestales con potencial restaurador (Marenco et al, 2003); sin embargo, existen especies que tienen semillas ortodoxas, es decir, tiene cubierta dura lo cual dificulta la aceleración de su germinación tal como ocurre con O. pyramidale (Herrera & Alizaga, 1999).…”

“…pyramidale ha sido objeto de múltiples estudios debido a su importancia ecológica y su potencial para recuperar áreas degradadas (Whitmore & Wool-Khoon, 1983;Toledo-González et al, 2019). Tiene amplia distribución geográfica que va desde las Antillas, suroeste de México, Ecuador, Colombia, Brasil y Bolivia (Sandi & Flores, 2010) y es pionera e indicadora de paisajes degradados y recién perturbado (Whitmore & Wooi-Khoon, 1983;Marenco et al, 2003).…”

Introducción: la Ochroma pyramidale es una especie con alto potencial restaurador y se adapta fácilmente en áreas perturbadas; sin embargo, la germinación de la semilla se ve afectada por ser ortodoxa y experimentar latencia. Vacío de conocimiento: variación de la capacidad germinativa entre distintos tratamientos y condiciones ambientales. Propósito del estudio: evaluar el porcentaje de germinación de semillas de O. pyramidale por medio de diferentes métodos de escarificación química. Metodología: se aplicó un diseño experimental de tres bloques, tres repeticiones y 15 unidades de ensayos. Los tratamientos fueron: T1 (agua caliente a 80°C), T2 (NaCIO al 0,5%), T3 (NaCIO al 1,0%), T4 (NaCIO al 2,0%), T5 (HCl al 1%). Resultados y conclusiones: la germinación de semillas de O. pyramidale en todos los tratamientos inició al cuarto día después de la siembra con algunas diferencias de semillas germinadas entre tratamiento con respecto al primer día de germinación con algunas variaciones entre tratamientos. El mayor porcentaje de germinación ocurrió en el tratamiento 1 (T1) con 88 semillas (59%), seguido del tratamiento 2 (T2) con 65 (43%). El tratamiento 1 (agua 80°C) tuvo mayor influencia en la germinación de semillas de O. pyramidale. Por lo tanto, se concluyen que los tratamientos por ebullición no solo contribuyen en el incremento de la germinación, sino que además las semillas logran mayor velocidad germinativa.
