Can Electrical Conductivity Predict Seed Germination of Three Pinus Species?

The potential of using the electrical conductivity method to predict seed germination of Pinus pinea, P. halepensis and P. nigra was investigated. Seed lots with low germination presented high conductivity values while those with high germination presented lower conductivity values after 48 hours of incubation. Based on linear regression analysis models with outlier remove analysis, high regression coefficients were obtained suggesting that it is possible to predict germination of the specific species through a quick electrical conductivity test.
