This research was aimed at determining which variables of seed analysis affects most stored seed quality of native species of Rio Grande do Sul State and verify its relationship with germination percentage of normal seeds. Data related to seed analysis of eight forest species were obtained from the State Foundation for Agricultural Research and a path coefficient analysis was conducted to obtain the relationship among purity of the lots, weight of a thousand seeds, humidity, percentage of normal and anormalous seedlings, firm and dead seeds obtained from batches stored in the laboratory. The percentage of normal seedling presented higher significant relationships with the variables weight of a thousand seeds, humidity and percentage of dead seeds.
