摘要：

本研究旨在探讨不同浓度赤藓糖醇对甜菜种子‘TD801’发芽特性的影响，以期为甜菜种子包衣技术提供科学依据。实验设计包括3个赤藓糖醇浓度（5、7.5、10 mmol/L）和3个处理时间梯度（8、16、24 h），形成9组不同的处理条件。通过与对照组(CK)比较，分析各处理条件下的种子发芽势、发芽率、发芽指数、活力指数以及相对电导率等指标变化。实验结果表明，所有处理组相较于对照组均显示出促进甜菜种子引发的效果。具体而言，处理后种子的发芽势较对照提高了4个百分点，最高12.33个百分点；发芽率比对照CK提高最低9个百分点，最高12个百分点；发芽指数比对照CK提高最低28.92%，最高60.74%；活力指数比对照CK提高最低69.45%，最高116.81%；相对电导率与对照CK比较均有降低，最低下降58.26个百分点，最高下降83.10个百分点。当浓度为5 mmol/L，8 h时，对提升发芽势效果较好；当浓度为5 mmol/L，24 h时，发芽率的效果更好；当浓度为5 mmol/L，16 h时，对发芽指数和活力指数的影响较好；浓度为10 mmol/L，时间为24 h对相对电导率效果更好。综上所述，赤藓糖醇处理能够有效提高甜菜种子的萌发性能，其中以5 mmol/L浓度和16 h的处理时间最为显著，为甜菜种子包衣提供了重要的参考信息。

Abstract:

To assess the impact of varying erythritol levels on seed germination and to provide a foundation for selecting sugar beet seed coating, the seeds of sugar beet 'TD801' were used as the test material in this study. The three concentration gradients (5, 7.5, 10 mmol/L) and three hour time gradients (8, 16, and 24 h) were set up, and then 9 treatments were used to determined the indexes. The germination potential was increased by 4%-12.33% in comparison to the control CK; the rate of germination was raised by 9%-12% compared to the control CK; and the germination index was also augmented by 28.92%- 60.74% compared with the control CK; the vitality index was increased by 69.45%-116.81% compared with the control CK; and the relative electrical conductivity was decreased by 58.26%-83.10% compared with the control CK. When the concentration was 5 mmol/L for 8 h, it had a better effect on improving germination potential; when the concentration was 5 mmol/L for 24 h, the effect of germination rate was better; when the concentration was 5 mmol/L for 16 h, it had a better effect on germination index and vitality index; when the concentration was 10 mmol/L for 24 h, it had a better effect on the relative electrical conductivity. The 9 treatments had the effect of promoting the initiation of sugar beet seeds, and a greater overall effect on seed germination of sugar beet was observed when the concentration of erythritol solution was 5 mmol/L for 16 hours.
