摘　　要：为了研究柠檬酸作为引发剂对甜菜单粒种引发的影响效果,并为甜菜种子包衣剂物料的选择提供依据。试验以甜菜单粒种1113×NY051为材料,不同浓度柠檬酸为引发剂,用直接测量法得到发芽势、发芽率等数据。结果表明,处理甜菜单粒种时,不同浓度柠檬酸和不同时间梯度的9个处理都能够有效地促进材料1113×NY051的发芽势、发芽率、发芽指数和活力指数,降低电导率。其中,5 mmol/L柠檬酸对甜菜种子1113×NY051在8、12、24 h 3个不同时间情况下的发芽势、发芽率、发芽指数和活力指数指标均高出对照组(CK),电导率低于对照组(CK)。不同浓度的柠檬酸能显著促进种子萌发,随着处理时间的变化和试剂浓度的不同对引发效果均有不同影响。In order to study the effect of citric acid as initiator on sugar beet single seed priming, and to provide a basis for the selection of sugar beet seed coating material, in this experiment, sugar beet single seed1113×NY051 was used as material, citric acid with different concentrations was used as initiator, and the data of germination potential and germination rate were obtained by direct measurement method. The results showed that the 9 treatments with different concentrations of citric acid and different time gradients could effectively promote the germination potential, germination rate, germination index and vigor index of 1113×NY051, and reduce the specific conductivity. Among them, the germination potential, germination rate, germination index and vigor index of 1113×NY051 beet seeds treated with 5 mmol/L citric acid at 8, 12 and 24 h were higher than those of the control group(CK), and the specific conductivity was lower than that of the control group(CK). Different concentrations of citric acid could significantly promote seed germination, and different treatment time and reagent concentrations had different effects on seed germination.
