Physiological potential of soybean seed and your relationship with seedling emergence in the field

The objective of this study was to evaluate soybean seed vigour and verify seedling emergence in the field. The tests for soybean seed vigour in the three cultivars were seedling field emergence, germination, seedling emergence in sand substrate, tetrazolium and electrical conductivity. There was no difference in germination and vigour between studied varieties. The determining factor in the experiment was time of planting, in which the lowest germination index occurred during the dry season
