Electrical Conductivity Relates Seed Germination and Seedling Emergence in Tagetes Seed Lots

In this study, we tested whether electrical conductivity of solute leakage was related to seed germination, mean germination time, 24th hour seed germination, seedling emergence percentage, mean emergence time and seedling dry weight in nine different tagetes seed lots. Normal seed germination percentages of seed lots ranged between 55 and 96 %, and electrical conductivity values were between 151 and 770 µScm⁻¹g⁻¹. Seedling emergence ranged between 68 and 95 %, mean emergence time was 3.9 to 5.1 days, and seedling dry weight 3.1-8.1 g/plant. Electrical conductivity was significantly related to normal germination (R²=0.64, p
