Good quality seeds are indispensable for successful crop establishment. A more precise analysis of seed quality requires a complementation of the information supplied by the germination with vigor tests to allow selection of the best lots for commercialization and sowing. Among these tests, the electric conductivity test is important. The objective of this study was to develop a suitable methodology for the electric conductivity test in mung bean seeds, with treatments of different imbibition periods and seed numbers. Six seed lots were used with the following treatments: 100, 75 and 50 seeds imbibed in 75 mL of 25 °C distilled water, and evaluations after 3, 6, 9, 12, and 15 hours of imbibition. The electrical conductivity test done with four subsamples of 50 pure seeds soaked in 75 mL of distilled water at 25 °C, permits a separation of the lots after three hours of soaking, and this procedure would make a quality evaluation of mung bean seeds viable.
