The objective of this work was to propose patterns for standardization of the indexes of analyses of seeds forest species. Thus, it was used results of the analysis of seeds of forest species from 1997 until 2007, belonging to the archives of Laboratório de Análise de Sementes da Fundação Estadual de Pesquisa Agropecuária (FEPAGRO - Laboratory of Seeds Analysis of Agricultural Research State Foundation - FEPAGRO - located in Santa Maria, Rio Grande do Sul. The limits of reliability were constructed from an analysis of data normality and the use of evaluation criteria for pseudo-sigma. The confidence limits set a minimum acceptable value so that a plot of seeds can be commercialized, proposing that the germination values within the confidence limits which are very low or low must be discarded, because they do not present acceptable indices of germination.
