Effects on the Germination of Sugar Beet Seeds: Different Concentrations of PEG

doi:10.11924/j.issn.1000-6850.casb18110090

Abstract

Abstract: To study the effect of different concentrations of PEG-6000 on the germination of sugar beet seed at 23℃, and lay the foundation for sugar beet seed initiation research, in this study, the sugar beet seed of TD305 was used as the experimental material, the concentrations of PEG-6000 were 10%, 20%, 40% and 60% and the treatment time was 24 h, 48 h and 72 h, respectively. The germination potential, germination rate, germination index and vigor index were determined. The results showed that 40% and 60% of PEG-6000 promoted the germination of sugar beet seed by 24 h. 20% and 40% of PEG-6000 promoted the germination of beet seed by 48 h. 10%, 20% and 40% of PEG-6000 promoted the germination of beet seed by 72 h. The PEG treatment showed that the germination potential, germination rate and vigor index were the highest after soaking in 40% of PEG-6000 for 72 h. The germination index was the highest after soaking in 60% of PEG- 6000 for 24 h. At room temperature, the optimum concentration of PEG-6000 could improve the vigor index of sugar beet seed.
