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. / O presente trabalho teve como objetivo diagnosticar a cadeia produtiva de sementes de oito espécies nativas do cerrado, na região metropolitana de Goiânia. A implementação da lei 10.711 de 2003 tem como intuito gerir a cadeia produtiva de sementes e cria o Sistema Nacional de Sementes e Mudas (SNSM), com objetivo de garantir a identidade e a qualidade das sementes comercializadas. Conjuntamente com esta lei, existe a Instrução Normativa do MAPA nº 56/11 que institui o credenciamento do coletor de sementes florestais, junto ao RENASEM e declaração de adimplência junto ao MAPA, sendo importante aporte legal na cadeia produtiva de sementes nativas, pois traz consigo o conhecimento sobre a procedência das sementes coletadas e também a exigência sobre a qualidade das sementes comercializadas, atestada pelas análises realizadas por laboratórios credenciados ao MAPA. Foram realizadas visitas em 28 viveiros e todos apresentaram descumprimento sobre a legislação que rege a cadeia produtiva de sementes e mudas. A maioria dos produtores de mudas obtém suas sementes por meio de coleta própria e realizam de forma inadequada não cumprindo as normativas que regem o setor. A quantidade de sementes obtidas supre apenas a demanda de sua produção, havendo somente 03 viveiros que comercializam sementes, mesmo assim de forma esporádica. Análises realizadas em oito espécies florestais nativas do cerrado não apresentaram diferença significativa nos testes de germinação e umidade das sementes, apresentando diferença somente no peso de mil sementes, que não apresenta literatura abrangente, mas que está diretamente ligado na comercialização das sementes.
