In order to determine the physiological quality of seed lots the electrical conductivity test has shown to be efficient due to its speed and ease of execution. The objective of this study was to evaluate the electrical conductivity test, considering water volumes, number of seeds and conditioning temperatures, in order to establish the methodology more suitable for batch stratification. Four batches of flax seed of the golden group were used. Initially, water content, germination, first germination count, seedling emergence and emergence speed index were determined. The electrical conductivity test was performed with the following variations: 25 and 50 seeds soaked in 25, 50 and 75 mL of distilled water at temperatures of 25 and 30 ° C, with readings 24 hours of imbibition. The most suitable condition for the electrical conductivity test of flax seeds is the soaking of 25 seeds in 75 mL of water at 30ºC.

Keywords : germination; “Flax”; lots; physiological quality.
