Seed and post-seminal development morphology on Bromeliaceae species

(Seed and post-seminal development morphology on Bromeliaceae species). The aim of this study was to characterize the seeds, providing information about germination type and seedling rate. in addition to describe the post-seminal development morphology of the six species of Bromeliaceae. The results showed that (lie germination is epigeal with cryptocolylar seedlings. Maximum germination percentage was over 80%, for all species, indicating high physiological quality of the seeds. Germination and seedling rate was 4-15 and 8-18 days, respectively. Seeds are filiform to elliptical, smooth or with flight apparatus. The most relevant morphological characters for distinguishing among genera and subfamilies are shape and appendices of the seeds, form and size of the cotyledonal sheath, hypocotyl and primary root, providing information on taxonomic, ecological and seed technology studies.
