摘要: 为了研究不同浓度PEG-6000在23℃时对甜菜种子萌发的影响,为甜菜种子引发研究奠定基础,本研究利用甜菜种子TD305为试验材料,分别采用浓度为10%、20%、40%和60%的PEG-6000,时间分别为24 h、48 h和72 h对甜菜种子进行处理,对发芽势、发芽率、发芽指数、活力指数进行测定。结果显示,处理时间为24 h时,40%和60%的PEG-6000对甜菜种子萌发有促进作用;处理时间为48 h时,20%和40%的PEG-6000促进甜菜种子萌发;处理时间为72 h时,10%、20%和40%的PEG-6000可促进甜菜种子萌发。PEG处理比对表明,40%PEG-6000浸泡72 h后的发芽势、发芽率和活力指数最高,60%PEG-6000浸泡24 h后的发芽指数最高。常温时,适宜浓度PEG-6000可提高甜菜种子的活力指标。

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.
