| Abstract | The Bromeliaceae family mostly originated in the Americas except one species, Pitcairnia feliciana, which is native to Africa. The Atlantic Forest biome is home to the largest number of species of bromeliads. The genres that have greater representation are catopsis, Tillandsia and Vriesea. Bromeliads play an important role, with benefits to the plant and animal life in the wild and also of economic interest because of its ornamental potential. The conservation in situ demonstrates great importance with regard to the maintenance of genetic variability as retains species in their natural environment. However, the removal of vegetation cover most of the forests, has threatened extinction of countless species. Therefore, it is necessary efforts for its conservation of these habitats. The objective of this study was to establish the criteria and procedures for the formation of an ex situ germplasm collection of bromeliads of Araucaria Forest and Dense, as well as the characterization and identification of the collected species. The gathering took place in the mixed rain forest (FOM), around the Campus Headquarters UFSC and Curitibanos region, SC. The collections of tropical rain forest (FOD) were performed at the Experimental Station of Epagri in Itajaí, SC. The work began by establishing an in vivo collection of stock plants that are represented by an average of two to three individuals per species. The plants were planted in pots containing as substrate a mixing commercial substrate Macplant and litter, which consists of pine bark, vermiculite, correction of acidity and fertilizer, its holding capacity is 60%, the exchange capacity cation (CTC) is 200 mmol c / Kg and has solid physical nature. The plants were kept in a greenhouse and then transferred to the nursery in a greenhouse. The collection currently has about 11 genera (Aechmea, Alcantarea, Ananas, Bromelia, Dyckia, Gusmania, Neoregelia, Nidularium, Quesnelia, Tillandsia and Vriesea) totaling 31 species. From this, the maintenance of these species of bromeliads in the collection will allow quick access for future research studies or as didactic structure taxonomy, reproduction and ornamentation and landscaping on the Campus of Curitibanos. Therefore, it is essential to the continuation and expansion of this work to increase the representativeness of the species found in the state. |
