Resumo: | In a program of seed quality assurance, the evaluation of seed vigor is fundamental and necessary to the global production process outcome. The objective of this study was to evaluate the efficiency of the precocity of primary root emission test, for the substrates paper roll, on paper and between papers, on vigor of pearl millet seeds. Ten seed lots evaluated in four replication of 100 pearl millet seeds cultivar ADR 500 were sown in three different humidified substrates: between papers, paper roll and on paper. These were incubated at a temperature of 20-30 degrees C. Fifteen hours after the germination test was established, the emission of seed primary roots started to be observed every 2 hours up to 25 hours and then after 48 hours. For the comparison among lots, seeds were also evaluated by moisture content, weight of 1000 seeds, germination and vigor (first count, electrical conductivity, accelerated aging and seedling emergence). The statistical design was completely randomized, and the means comparisons were accomplished by the Tukey test at 0.05 level of probability. It was concluded that the precocity of primary root emission test on paper is promising for vigor evaluation of pearl millet seeds. |
