Última Development of methodology to test the electrical conductivity of Marandú grass seeds Rev. Ciênc. Agron. Melo,Paulo Alexandre Fernandes Rodrigues de; Martins,Cibele Chalita; Alves,Edna Ursulino; Vieira,Roberval Daiton. ABSTRACT The electrical conductivity test enables the evaluation of seed vigor for a maximum period of 24 hours, but the need to count the seeds to obtain a sample for analysis makes it difficult to apply this test to small seeds, such as forage grasses. The objective of this study was to establish a practical methodology for testing the electrical conductivity of Brachiaria brizantha (Hochst. Ex A. Rich.) Stapf ‘Marandú’ seeds and to estimate its effect on seedling emergence in the field. The water content, germination, first germination count, first emergency count, percentage, and rate of seedling emergence speed in the laboratory, seedling emergence in the field, and electrical conductivity of eight batches of seeds was analyzed. In the last test, the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Brachiaria brizantha; Forage grasses; Physiological quality; Vigor tests.

The growing demand for high quality soybean [Glycine max (L.) Merrill] seeds requires a precise seed quality control system from the seed industry. One way to accomplish this is by improving vigor testing. Cold test has been traditionally employed for corn seeds. However, it has also been used for other seed crops such as cotton (Gossypium spp.), soybean (Glycine Max), dry bean (Phaseolus vulgaris) and pea (Pisum sativum). This study was carried out with the objective of adjusting an alternative procedure for the cold test to determine soybean seed vigor. Six commercial soybean seed lots of the cultivar BRS 133 were used. The physiological potential of the seed lots was evaluated by germination on paper towel and sand box, seedling field emergence,...
