Resumo

The objective of this work was to compare different tests used to evaluate soybean seed vigour and to verify their relationship with seedlings emergence in field. Thus, the soybean seed vigour of ten cultivars was evaluated by the following tests: seedling emergence in field, standard germination, seedlings emergence in sand seedbed, speed of emergence in sand seedbed, accelerated aging, modified cold test, tetrazolium (1-3 and 1-5) and electrical conductivity. The accelerating aging, standard germination, tetrazolium and electrical conductivity tests showed higher correlations with field emergence. The results obtained from laboratory tests and seedlings emergence in field should not consider only the correlation analysis.
