Abstract
El trabajo estuvo encaminado a determinar el método que se ha de utilizar con las semillas de Pinus maestrensis a fin de aumentar la capacidad germinativa de las mismas. Con este propósito se aplicaron 15 tratamientos que contemplan la inmersión a temperatura ambiente y a 5ºC durante 24 y 48 horas, así como la combinación de la inmersión 24 y 48 horas con la estratificación 15 y 30 días, respectivamente. Los resultados indicaron que los tratamientos que combinan la inmersión 24 horas, a temperatura de 5ºC y estratificación 15 y 30 días respectivamente y estratificación 15 y 30 días por separado, permitieron obtener los mayores resultados en las tres Estaciones Experimentales.
