dc.description.abstract[EN] Seed vigour is a character of great interst, due to its high incidence on the stablshment of an optimum plant density necessary to reach a good productivity. Seed vigour has shown a great amount of intraspecific variability in many different crops, offering the possibility for the application of plant breeding programmes for its improvement. Direct estimation of seed vigour through field emergence is very affected by environmental conditions, leading to a lack of precision and repeteability of the test. In more than 40 species studied in this literature review, there are 40 to 50 laboratory test procedures for measuring seed an seedling vigour. Seed vigour tests are divided into direct and indirect tests. Indirect tests are subdivided into physiological, biochemical, and physical tests. The direct tests reviewed have been accelerated aging, controlled deterioration, soak test, osmotic stress, cold test, cool germination test, and brick grit. The physiological tests studied have been speed of germination, seed vigour classification, and seedling growth rate. As biochemical tests, we considered tetrazolium test, aleurone tetrazolium test, conductivity test, respiration, GADA, and ATP content. We include seed's size, weigth, and density as physical tests. A table including species and seed vigour tests used, is presented.en_US
