The Same Concentration of PEG: Effects on the Germination of Different Sugar Beet Seeds

doi:10.11924/j.issn.1000-6850.casb18110105

Abstract

Abstract: To research the effect of the same concentration of PEG- 6000 on different sugar beet seeds germination at 23℃, and lay the foundation for sugar beet seeds initiation, the 40% PEG-6000 was used to treat beet seeds of TD701(2017), TD703(2016), TD801(2015) and TD301(2014). The soaking time was 24 h, 48 h and 72 h. The germination potential, germination rate, germination index and vigor index were measured. The results showed that TD701 (2017) and TD801 (2015) had better germination effect under 24 h treatment. TD701 (2017) and TD703 (2016) had better germination effect under 48 h treatment. TD701 (2017), TD703 (2016) and TD801 (2015) had better germination effect under 72 h treatment. The comprehensive comparison showed that the germination potential of TD801 (2015) was the highest under 40% PEG-6000 for 24 h. The germination rate of TD801 (2015) was the highest under 40% PEG-6000 for 24 h. The germination index of TD703 (2016) was the highest under 40% PEG-6000 for 48 h. The vigor index of TD703 (2016) was the highest under 40% PEG-6000 for 48 h. The results indicate that the germination effect of sugar beet seeds is affected by different treatment time and the different storage years.
