Qualidade de sementes de Garapeira (Apuleia leiocarpa (Vogel) J.F. Macbr.)provenientes de diferentes matrizes

Abstract

Forest species are of significant importance in economic, social, and especially ecological contexts, due to their biodiversity and the environmental services they provide. In this regard, studies on seed quality from different matrices are essential for initiating the replanting process of areas affected by anthropogenic factors such as overexploitation, wildfires, and improper natural resource use to supply industries. This study aimed to evaluate the seed quality of garapeira (Apuleia leiocarpa) from different matrices: JD-AF (José Dias - Alta Floresta), L NG1 (Luís - Nova Guarita 1), L-NG2 (Luís - Nova Guarita 2), L-NC (Luzinete - Nova Canaã), and O-NG (Odiva - Nova Guarita). The experiments were conducted in the Seed Laboratories, Environmental Sciences and Biodiversity Laboratory (LCAB), Phytopathology and Phytosanitary Laboratory (LFF), and the Greenhouse of the Agronomic Biotechnology Center at the State University of Maranhão, São Luís – MA, from September 2024 to April 2025. The results indicated that the JD-AF and L-NG2 matrices stood out for their germination speed, seedling growth, high germination rates, and absence of fungal contamination. In conclusion, the JD-AF and L-NG2 matrices presented the best physical, physiological, and sanitary quality
