Levantamento de dados de espécies florestais nativas do Cerrado: um meio para bancos de sementes implantados que permitem restauração e conservação de ecossistemas florestais

Abstract

Brazil is a country of great diversity, with forest species that stand out for their historical, ecological, economic and cultural importance. The present study aimed to survey and evaluate data related to seed production of forest species for implantation of a seed bank in the northern region of Minas Gerais. Sixty species were selected from phytosociological studies carried out in a riparian forest located in Lapa Grande State Park in Montes Claros. The study was conducted through literature reviews and the parameters evaluated were: ecological groups, seed behavior in storage and methods for seed quality evaluation. It was observed a higher concentration of species in the pioneer ecological group (55% of the species) and, in relation to the seed behavior in storage, 21.6% of the species were classified as orthodox and regarding the physiological quality evaluation of the seeds, commonly performed by germination test, data were observed for only 35% of the studied species and different methodologies were found for the same species. The information obtained in the present study shows that the northern region of Minas Gerais has great potential for the implementation of a seed bank, although there is a lack of information related to seed production of native forest species, a fact that motivates the development of more research that will contribute to the conservation of local species.
