Viabilidad de semillas de guayacán (Guaiacum sanctum L., Zygophyllaceae) posterior a dos tratamientos pregerminativos

Abstract

Guaiacum sanctum L. es una especie arbórea de crecimiento lento que pertenece a la familia Zygophyllaceae, habita en el bosque seco subtropical y tropical. El objetivo de este estudio fue analizar la viabilidad de semillas de guayacán, posterior a dos tratamientos pregerminativos. La colecta de semillas se realizó en las cercanías del estadio Carlos Miranda, en el departamento de Comayagua, Honduras. Una vez colectadas las semillas se empleó corte longitudinal en la testa y lixiviación, como tratamientos pregerminativos y posteriormente se aplicó pruebas de flotabilidad y de tetrazolio para el análisis de viabilidad. Se obtuvo como resultados un mayor número de semillas viables, registrando los porcentajes de viabilidad más altos, en aquellas a las que no se les aplicó tratamiento pregerminativo. En cuanto a las pruebas de viabilidad se demostró que la más efectiva es la de tetrazolio, ya que permite observar de forma directa el embrión y el estado de los tejidos embrionarios. El análisis de viabilidad contribuyó a conocer la posible influencia de dichos tratamientos en la viabilidad de las semillas. Estos son factores importantes ya que se encuentran relacionados con la germinación de esta especie vegetal de especial interés económico y forestal.
