摘要
以丹参种子为对象,研究不同储存温度及储存方式下丹参种子的发芽情况,比较不同处理方法对种子发芽率的影响。结果表明,随着储存年份的增加,常温下丹参种子发芽率、发芽势和发芽指数呈显著降低的趋势(p<0.05),而-18℃和5℃储存下,丹参种子发芽率、发芽势和发芽指数无明显变化(p>0.05)。在常温的不同储存方式下,随着储存时间的增加,网袋中丹参种子发芽率显著降低(p<0.05),而塑料袋中的丹参种子发芽率在前5个月无明显降低(p>0.05)。研究表明,丹参种子塑料袋包装后于5℃储存,能有效保持丹参种子活力。
In order to study the germination temperature and storage mode of Salvia miltiorrhiza seeds,the germination conditions of S.miltiorrhiza seeds under different storage temperature and storage mode were studied,and the effects of different treatment methods on seed germination rate were also compared.The results showed that the germination rate,germination potential and germination index of S.miltiorrhiza seeds decreased significantly under normal temperature with the increase of storage years(p<0.05),while the germination rate,germination potential and germination index of S.miltiorrhiza seeds did not change significantly under-18℃and 5℃storage(p>0.05).Meanwhile,under different storage methods at room temperature,the germination rate of S.miltiorrhiza seeds in the net bag decreased significantly with the increase of storage time(p<0.05),while the germination rate of S.miltiorrhiza seeds in the plastic bag did not decrease significantly in the first 5 months(p>0.05).The results showed that S.miltiorrhiza seeds stored at 5℃after packaged in plastic bags could effectively maintain the vigor of salvia miltiorrhiza seeds.
