EFICIÊNCIA DO USO DA MASSA HECTOLITRO COMO TESTE RÁPIDO DE VIGOR DE SEMENTE DE TRIGO (Triticum aestivum)

The objective was to evaluate the correlation between hectolitre bulk (PH) and seed vigor of wheat through different vigor tests, to ascertain whether the use of PH is effective when used as a rapid test for physiological quality. We used lots of wheat test PH 69.0, 73.5, 75.5, 77.5 and 79.5. The laboratory tests were based on the methodology proposed by the Rule of Testing, and count of normal seedlings at 4 days and 8 days, determining the root length and shoot, and fresh and dry mass. The field tests conducted following methodology POPINIGIS (1977) tests count emerged plants at 21 days, fresh and dry mass of shoots at 21 days and the index of germination speed (IVE), as well as the electrical conductivity test and leaching of potassium. The results obtained can be inferred that the test to count 4 days, green mass and dry weight at 8 days, plants and bad plants hard to 8 days, plant length, speed of emergence and emerged plants in the field 21 days, the fresh and dry the field for 21 days did not show good correlation with the bushel weight, since the methods of normal plants and unusual plants at 8 days and root length showed an inverse correlation, and the results of shoot length , electrical conductivity and potassium leaching showed a positive correlation with the PH.
