摘要: [目的]为了筛选出促进甜菜种子萌发的引发剂,研究不同引发剂对甜菜种子萌发的影响,为甜菜丸粒化物料奠定基础, [方法]本研究利用甜菜种子TD305为试验材料,采用蒸馏水、水杨酸、赤霉素作为引发剂对甜菜种子进行处理,设置不同浸泡时间、不同浓度梯度,并对发芽势、发芽率、发芽指数、活力指数进行测定。[结果] 结果显示蒸馏水对于种子萌发时间在30min左右为宜。水杨酸处理甜菜种子的适宜浓度为0.05、0.1、0.2和0.5 mmol/L。赤霉素处理对甜菜种子的适宜浓度为0.05、0.1和0.2 mmol/L。[结论]结果表明在适宜时间和浓度下,蒸馏水、水杨酸、赤霉素这三种引发剂均对甜菜种子萌发有一定促进作用,但时间过长或者浓度过高反而有抑制作用。三种引发剂比对结果表明,发芽势:蒸馏水>水杨酸>赤霉素;发芽率:蒸馏水> 赤霉素>水杨酸;发芽指数:蒸馏水> 赤霉素>水杨酸;活力指数:赤霉素>蒸馏水>水杨酸。

Abstract: The study aims to screen out initiators for promoting the germination of sugarbeet seeds. The effectsof different initiators on the germination of sugarbeet seeds are studied to provide references for the granulation of sugarbeet pellets. Sugarbeet seed‘TD305’was used as the experimental material, the seeds were treated with distilled water, salicylic acid and gibberellin as initiators. Different soaking times and concentration gradients were set, and the germination potential, germination rate and germination index and vitality index were measured. The results showed that distilled water was suitable for seed germination time of about 30 min. The suitable concentration of salicylic acid was 0.05, 0.1, 0.2, 0.5 mmol/L. The optimum concentration of gibberellin was 0.05, 0.1, 0.2 mmol/L. At the appropriate time and concentration, distilled water, salicylic acid and gibberellin all promoted the germination of sugarbeet seeds, but the too long time or the too high concentration could inhibit the germination. Comparing the three kinds of initiators, in terms of germination potential, distilled water> salicylic acid> gibberellin; in terms of germination rate, distilled water> gibberellin> salicylic acid; in terms of germination index, distilled water> gibberellin> salicylic acid, and in terms of vitality
