The objective was to study the pre-germination treatment chive seeds with different concentrations of hydrogen peroxide. The experiment was conducted at the plant physiology laboratory belonging to the Federal University of Campina Grande (UFCG). The treatments were distributed in a completely randomized design with five concentrations of hydrogen peroxide (0.0, 0.015, 0.030, 0.045 and 0.060 mM) and four replications, totaling 20 experimental units. The seeds were soaked in dark colored containers for 24 hours at room temperature. It adopted the substrate moistened germination method (germitest paper) with the solutions at 25 °C. The productive system that included the number of germinated seedlings (NPG), seedling length (CP), seedling fresh mass (MFP), seedling dry mass (MSP), germination percentages (%G), speed index was evaluated, germination rate (IVG), average germination time (TMG) and average germination speed (VMG). Assessments were performed daily for 12 days after test installation. Pretreatment of seeds with hydrogen peroxide had a positive influence on the growth of chive seedlings. Given the results, it is recommended to pre-treat the chives seeds with 0.036 mM hydrogen peroxide.
