Investigación preliminar sobre el aislamiento e identificación de microorganismos en semillas de Pinus tropicalis
Main Article Content
Abstract
Debido a la importancia que tiene el control de enfermedades forestales, hemos encaminado el presente trabajo al aislamiento e identificación de patógenos en semillas de Pinus tropicalis Morelet procedentes de la zona de Macurije, provincia de Pinar del Río, por ser éstas las que presentan más baja y errática germinación. Se tomaron para este ensayo grupos de 200 semillas de la cosecha de 1982, las que fueron analizadas con desinfección en tres sustratos y a dos temperaturas; se realizaron dos repeticiones. Los datos fueron procesados estadísticamente. De los resultados obtenidos, el género Rhizopus es el que presenta mayor porcentaje de aparición.
