目的研究建泽泻种子贮藏特性。方法采用牛皮纸袋和玻璃瓶包装泽泻种子,分别放置于常温下、干燥器内和4~10℃冰箱内贮藏,每隔2个月调查各贮藏处理的发芽率。结果泽泻种子的发芽率随贮藏时间的延长逐渐降低,常温常规贮藏半年,发芽率下降一半,贮藏1年,几乎丧失生活力,可见泽泻种子是短命的种子;瓶装4℃~10℃低温保存1年,仍有45.1%的发芽率,较常规贮藏的发芽率提高40%。结论瓶装4℃~10℃低温适宜泽泻种子贮藏。
Objective To study the storage characteristics of Alisma orientalis seed. Methods Alisma orientalis seeds were packed in kraft paper bags and glass bottles and stored at room temperature, in desiccator and in refrigerator at 4 ~ 10 ℃. The germination rate of each storage was investigated every 2 months. Results The germination rate of Alisma orientalis seeds decreased gradually with the prolongation of storage time. The germination rate of Alisma orientalis seeds was half a year after storage at room temperature for half a year, and the germination rate was reduced by half and stored for 1 year. After 1 year of storage, the germination rate was still 45.1%, which was 40% higher than that of conventional storage. Conclusion Bottled 4 ℃ ~ 10 ℃ low temperature suitable for Alisma orientalis storage.
