Abstract
The study aimed to assess present the effects of water volume and imbibition periods on the application of electric conductivity test on crambe seeds. We used crambe (Crambe abyssinica Hochst) seeds of 5 lots, FMS Brilhante cultivar, provided by the MS Foundation, from properties located in different locations of Mato Grosso do Sul State, produced on the 2012 harvest. We used randomized block designs with four replicates. For the characterization of the lots, we conducted germination tests and emergence speed index. Posteriorly, we performed the electric conductivity test, using 25oC as imbibition temperature, four volumes of water (20mL, 30mL, 40mL and 50mL) and 5 imbibition periods (30, 60, 120, 240 e 360 minutes). We observed that the higher the volume the lower the quantity of electrolytes liberated by the seeds. The electric conductivity test was efficient in order to assess the vigor of crambe seeds. The volumes of 20 and 30mL, with imbibition period of 240 minutes, were the most favorable conditions in the conduction of our test.
