This work aimed to determinate the best water volume and immersion period used on electrical conductivity test for the evaluation of physiological potential of seed lots of canola. Four seed lots of canola were evaluated, which were firstly characterized with respect to quality through tests of germination, first germination count, seedling length and emergence on sand. The electrical conductivity test was carried out at 25ºC. Seeds were imbibed in 25 and 50 mL of distilled water during 4, 8, 16 and 24 hours. The experimental design used was completely randomized, with four replicates of 50 seeds. Data was analyzed in a factorial scheme with four seed lots, two water volumes and five immersion periods. The electrical conductivity test carried out under immersion of 50 seeds during 8 hours in 25mL at 25ºC of deionized water is efficient to evaluate the physiological potential of seed lots of canola.
