Morfología, dormición y germinación de semillas de Juglans neotropica Diels (Juglandaceae)

Abstract

Abstract: Morphosiological studies are important to establish different ecological strategies for the conservation of species and to know the dynamics of the communities in the face of environmental changes. The objective of this research was to generate information on the morphophysiological aspects that affect the germination process of Juglans neotropica seeds. We worked with seeds of five individuals, analyzed different morphological traits, aspects of the dormition, evaluating the speed of germination and using different treatments pre-germ. It was determined that the seeds have sizes of 3.75 cm and 3.64 cm transverse and longitudinal planes. It was to establish that the morphological characteristics of the seeds of j. neotropica with moisture content they are decisive for its process of imbibition and germination where obtained best results in seeds with opening on the base. We finally determined that despite the width and hardness of the testa in seeds, the testa is permeable to water, which could favour the germination of some seeds. Despite the hardness of the testa could cause physical dormancy in the seeds.
