Zusammenfassung: | The palo blanco (Ipomea arborescens) is a perennial tree belonging to the Convolvulaceae family, of ethnobotanical and forage importance. The objective of the work was to evaluate the percentage of germination in vitro with pregerminative treatments (mechanical scarification without AG3, mechanical scarification and concentrations of 0, 0.5, 1.0, 1.5 and 2.0 of AG3/mgL-1, without mechanical scarification and with concentrations of AG3 mentioned, and the control without mechanical scarification or AG3). The experimental design was completely randomized with a factorial arrangement of 3 treatments, 3 repetitions (25 seeds each) and a control, with a Tukey-Kramer ANDEVA and mean (α=0.05 %). The results did not show significant differences in the pregerminative treatments evaluated, except for the control that did not show germination. Germination was 98.33 to 99.66 %, there were 0.00 to 0.66 % of abnormal seeds, 98.66 to 99.66 % of normal seeds and 0.33 to 1.00 % of non-germinated seeds. The average height in the seedlings before transplanting was 8.58 cm. Transplant survival on the 9th and 16th day was 100 %, with an average height of 16.27 cm. The results indicate that I. arborescens seeds require pregerminative treatment (mechanical scarification) to germinate and perpetuate the species in the wild habitat.

El palo blanco (Ipomea arborescens) es un árbol perenne perteneciente a la familia Convolvulaceae, de importancia etnobotánica y forrajera. El objetivo del trabajo fue evaluar el porcentaje de germinación in vitro con tratamientos pregerminativos (escarificación mecánica sin AG3, escarificación mecánica y concentraciones de 0, 0.5, 1.0, 1.5 y 2.0 de AG3/mgL-1, sin escarificación mecánica y con las concentraciones de AG3 mencionadas, y el control sin escarificación mecánica ni AG3). El diseño experimental fue completamente al azar con arreglo factorial de 3 tratamientos, 3 repeticiones (25 semillas cada uno) y un control, con un ANDEVA y media de Tukey-Kramer (α=0.05 %). Los resultados no mostraron diferencias significativas en los tratamientos pregerminativos evaluados, excepto el control que no mostro germinación. La germinación fue 98.33 a 99.66 %, se presentó un 0.00 a 0.66 % de semillas ano |
