Electrical conductivity test in function of the period and the temperature of imbibition solution for seeds of pearl millet

Two experiments were carried out [with the purpose of studying] to study the effects of imbibition period and temperature of imbibition on the results of the electrical conductivity test for the evaluation the vigor of pearl millet to evaluate pearl millet (Pennisetum americanum L.) seeds vigor. In the first experiment was studied the imbibition periods of 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22 and 24 hours, [to the temperature of] at 25ºC were studied, and in the second at the temperatures of 20, 25, 30, 35 and 40ºC, (in a more promising imbibition period more promising of than the first experiment.????) AD Three seeds lots were compared, lot 1 represented by cv. Comum and the lots 2 and 3 by cv. BN2. Four replicates of 100 seeds in 100ml of imbibition water were employed for all the treatments. The experimental design was the complete entirely randomized block, with four replications for all the treatments. Results indicated that the period of imbibition period can be reduced to two hours and that in this period the temperature had little influence on the results. As such, 25ºC seems a convenient imbibition temperature for the conduction of this test.
