Abstract:

To determine the priming effect of different concentrations of cytokinin 6-BA on sugarbeet seeds, and to provide a basis for screening sugarbeet seed coating materials, in this study, TD802 sugar beet seeds were used as experimental materials, and 9 treatments with 3 concentrations and 3 time gradients were set up. The germination energy, germination rate, germination index and vigor index of beet seeds were determined by soaking and drying. The results showed that the germination energy, germination rate, germination index and vigor index of sugarbeet seeds treated with 0.1% 6-BA at 8, 12 and 24 h were higher than those of the control. The germination energy, germination rate, germination index and vigor index of sugarbeet seeds treated with 0.5% 6-BA for 8 h and 12 h were higher than those of the control. The germination rate, germination index and vigor index of sugarbeet seeds treated with 1% 6-BA for 12 h were higher than those of the control. Therefore, different concentrations of cytokinin 6-BA have different effects on the germination of sugarbeet seeds with different time, too long or too short treatment time could affect the triggering effect.
