The present work had as objective to diagnose the productive chain of seeds of eight native species of the cerrado, in the metropolitan region of Goiânia. The implementation of Law 10.711 of 2003 aims to manage the seed production chain and creates the National System of Seeds and Seedlings (SNSM), in order to guarantee the identity and quality of the seeds sold. Together with this law, there is the Normative Instruction of MAPA No. 56/11 that establishes the accreditation of the forest seed collector, together with RENASEM and declaration of compliance with the MAPA, being an important legal contribution in the native seed production chain, as it brings with it The knowledge about the origin of the seeds collected and also the requirement on the quality of the seeds commercialized, attested by the analyzes carried out by laboratories accredited to MAPA. Visits were carried out in 28 nurseries and all showed noncompliance with the legislation that governs the seed and seed production chain. Most seedlings producers obtain their seeds through their own collection and perform inadequately not complying with the regulations that govern the sector. The quantity of seeds obtained only supplies the demand for its production, and there are only three nurseries that commercialize seeds, even so in a sporadic way. Analyzes carried out on eight native forest species of the cerrado did not present a significant difference in germination and seed moisture tests, presenting only difference in the weight of one thousand seeds, which does not present a comprehensive literature, but which is directly related to seed commercialization.
