RESUMO:

In order to complement the information obtained by the germination test, the tests used to evaluate seed vigor, which are classified as physical, physiological, biochemical and resistance to stress. Inserted in the physiological tests, the seedling vigor classification test for the evaluation of seed lots has been little used, mainly with native forest species. Therefore, the objective of this study was to characterize the seedlings of Enterolobium contortisiliquum, Pityrocarpa moniliformis and Poincianella pyramidalis in relation to morphological aspects and to use them as specific parameters for the test of vigor classification of seedlings. The study was divided into three distinct stages: morphological characterization of the species, carried out from the germination test; physiological characterization of seed lots, through vigor tests; and seedling vigor classification, where the results obtained in the physiological tests were correlated with the percentage of normal seedlings "strong" obtained in each seed lot. The results showed that there was a difference in the physiological quality of the seeds of E. contortisiliquum, P. moniliformis and P. pyramidalis, and that the parameters adopted in the morphological characterization of strong normal seedlings were efficient in the classification of seeds vigor for the species under study.
