Vigor test in Dimorphandra wilsonii seeds depending on soaking and electrical conductivity Teste de vigor em sementes de Dimorphandra wilsonii em função da embebição e da condutividade elétrica

The objective of this work was to study the physiological quality of seed lots of Dimorphandra wilsonii as a function of soaking and electrical conductivity. The water content of seeds, germination rate, and the germination index for the characterization of the initial seed quality and the electrical conductivity test were evaluated, for which two volumes of deionized water solution (75 were tested and 100 mL) and three different residence times in the seed solution (24, 48 and 72 hours). The soaking periods showed no statistical differences, and use the solution with 75 mL for a period of 24 hours, associated with the germination test was able to separate plots with different levels of force, showing the superiority of lot 1 in relation to lots 2 and 3.
