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。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.
