The electrical conductivity test can provide important and complementary information on the physiological potential of seeds in a relatively short period of time, unlike the germination test which is completed in 28 days for yellow passion fruit seeds. Thus, the objective of this study was to evaluate the efficiency of the electrical conductivity test and to standardize the methodology to be for seeds of yellow passion fruit. Four seed lots were tested for germination and vigor (first count, accelerated aging, speed germination index and seedling emergence in green-house) including the electrical conductivity test, conducted with 25 and 50 seeds immersed in 50 and 75 mL of dionized water and the readings taken after 3, 6, 9, 12 and 24 hours of soaking. Only lot 2 showed reduced vigor appointed by the first count test, seedling emergence and electrical conductivity test. The vigor determination of yellow passion fruit through the electrical conductivity test can be performed using 50 seeds in 75 mL of dionized water, with 24 hours of soaking.
