GUEDES, Roberta Sales et al. Vigor tests in the evaluation of physiological quality of Erythrina velutina Willd. (FABACEAE- PAPILIONOIDEAE) seeds. Ciênc. agrotec. [online]. 2009, vol.33, n.5, pp.1360-1365. ISSN 1413-7054.  https://doi.org/10.1590/S1413-70542009000500023.

The application of vigor tests of seeds has been fundamental as a fast and efficient form of determination of physiological seed quality, highlighting the tests based on the performance of seedlings as one of the available options. The objective of this study was to evaluate the efficiency of different vigor tests for the determination of the physiologic quality of Erythrina velutina seeds. In five lots of E. velutina seeds, water content and seed weight were determined. Tests for germination were performed for field seedling emergence, speed germination and emergence index, and length and dry matter weight of seedlings from both the laboratory and from the field. Field tests (seedling emergence, speed emergence index, and dry matter weight of the aerial part of seedlings) are efficient in the separation of the seed lots of E. velutina in vigor levels.
