The work was carried out to compare methods of evaluation of broccoli seed physiological quality, including tests of germination, seedling emergence, accelerated aging (24, 48, 72 and 96 hours at 42°C) and electrical conductivity (0.5, 2, 4, 12 and 24 hours of imbibition at 25°C with 25, 50 and 75 ml of water). The tests of germination, seedling emergence and electrical conductivity (imbibition for 24 h with 25 ml of water) agreed in discriminating the vigour of seed lots. A acelerated aging at 42°C for 48 hours can also be used to distinguish vigour among seed lots.
