A New Approach to Determine Time and Temperature Combination for Electrical Conductivity Test in Sorghum
Keywords:Sorghum bicolor, Seed vigor, Cultivar, Temperature, Duration
AbstractThis study was conducted to determine a suitable time and temperature combination for the electrical conductivity test to be used in sorghum seeds. Fifty seeds known initial seed moisture content and weight of fresh and dead seeds (105Â°C for 6h) of seven sorghum cultivars were used as material. The electrical conductivities of soaking water were measured using an EC meter in 20, 25 and 30Â°C for 4, 8, 12 and 24 h using 50 mL deionized water. The experimental design was three factor factorial (7 × 3 × 4) arranged in a completely randomized design; with four replications and 50 seeds per replicate. The results showed that increased time and temperature caused a remarkable increase in EC values of all of the cultivars. Temperature significantly affected the electrical conductivity values and the best results were obtained at 25Â°C. The cultivars with the lower germination percentage gave the higher electrical conductivity value. Dead seeds always gave higher electrical conductivity at 25Â°C for all periods. It was concluded that the temperature of 25Â°C and 24 h was the optimum combination for the electrical conductivity test in sorghum.
